PowerBlock Holdings, Inc. v. iFit Inc.: Machine is eligible when it is “sufficiently specific” and “consists of parts, or of certain devices and combination of devices.”
The Federal Circuit reversed the district court’s dismissal of PowerBlock’s claims under § 101, holding that claims directed to selectorized dumbbells with motorized weight selection were not abstract ideas. The court emphasized that claim 1 recited a specific mechanical configuration—nested weight plates, a movable selector, and an electric motor physically coupled to move the selector—that constituted a “technological improvement” rather than a result-oriented abstraction. Unlike prior cases involving “do it on a computer” patents, the claims here were directed to a concrete machine with defined structural limitations. The court also rejected iFit’s argument that conventional dumbbell components should be ignored, clarifying that § 101 does not allow old elements to be read out of the eligibility inquiry. Because the claims as a whole recited a specific implementation of a mechanical improvement, they were patent-eligible at Alice step one.
Recentive Analytics, Inc. v. Fox Corp.: Claims that do no more than apply established methods of machine learning to a new data environment are not patent eligible.
The Federal Circuit affirmed the district court's holding that the claims were ineligible under Alice because they are directed to the abstract idea of applying generic machine-learning techniques in a particular data environment with no inventive concept.
Recentive argued in its briefs that its application of machine learning is not generic because “Recentive worked out how to make the algorithms function dynamically. . . .” But the court held:
Even if Recentive had not conceded the lack of a technological improvement, neither the claims nor the specifications describe how such an improvement was accomplished. That is, the claims do not delineate steps through which the machine learning technology achieves an improvement.“
Patent Docs (linked below) notes that the Court hints that more detail in the claim and the specification regarding the technical improvement, such as the training process, could avoid a finding of ineligibility.

US Synthetic v. ITC: It's legal error to require patentee to prove patent eligibility when invalidity is asserted
The Federal Circuit reversed the ITC's § 101 holding that asserted composition-of-matter claims were not directed to an abstract idea at Alice Step One where quantified material properties correlate to structure. The court applied APA review to ITC determinations, noting that § 101 Step One was resolved from the intrinsic record rather than expert testimony relied upon at the hearing.

United Services Automobile Association v. PNC Bank: Mobile check deposit using cell phone lacks inventive concept
The Federal Circuit held the asserted claim is directed to an abstract idea (mobile check deposit) and lacks an inventive concept under Alice step two, reversing the district court’s contrary § 101 summary-judgment ruling.
Holding:
In Alice step one, the court concluded that the claim merely automated conventional human and banking activities such as photographing, recognizing, and verifying check data, implemented through generic mobile-device functions. The specification’s discussion of optical character recognition and error checking did not supply a technological improvement because the claim failed to specify how those operations were performed. The court distinguished Enfish and McRO, emphasizing that the claim recited results, not the specific rules or algorithms that would make the process non-abstract. In Alice step 2, the court found no inventive concept in the ordered combination of elements. Use of routine components (mobile phones, OCR, and wireless networks) to carry out known data-capture and transmission functions was conventional and insufficient to confer eligibility. The court rejected arguments that factual disputes over conventionality precluded summary judgment, noting that OCR and mobile capture systems were well known in the art.
Because all asserted patents in the consolidated appeals had been found unpatentable or ineligible, the panel dismissed the remaining cross-appeal on damages as moot and entered judgment reversing the district court and invalidating the ’638 patent under § 101.

Sage Products v. Coke Morgan Stewart et al.: “Sterile” means “sterilized”
The Federal Circuit affirmed the Board's finding that claims were anticipated because the prior art disclosed each challenged limitation and could rely on expert testimony to interpret what the prior art reference disclosed for anticipation purposes, including limitations not expressly spelled out. In particular, the court found that a foreign regulatory document's use of the term “sterile” can satisfy claims requiring “sterilized,” as understood by a person of ordinary skill in the art.

Honeywell Int'l v. 3G Licensing: Any need or problem that the patent addresses can supply a reason to make the claimed modification; the patentee's avowed purpose does not control.
The Federal Circuit reversed a Board's determination that claims directed to codeword formatting for error correction is not obvious, finding the Board improperly relied on the motivation of the patent in suit. The Board acknowledged that the only difference between claim 1 and the prior art is that the 1 and 0 in the last row of basis sequences table were switched. The court held that, contrary to KSR, the Board ignored principle that any need or problem known in the field of endeavor at the time of the invention and addressed by the patent can provide a reason for combining the elements in the manner claimed.

Janssen Pharma. v. Teva Pharma USA: Presumption of obviousness where ranges overlap
The Federal Circuit held that, in overlapping-range cases, a challenger may establish a presumption of obviousness, i.e., a prima facie case of obviousness, by showing that the claimed values fall within or near prior-art ranges under circumstances where a skilled artisan would have been motivated to optimize and would reasonably expect similar properties. That showing shifts the burden of production, not the burden of persuasion.

Shockwave Medical v. Cardiovascular Systems: Routine design choice
The Federal Circuit reversed the Board's determination of non-obviousness as to claim 5, saying “The Board [failed] to consider the combined teachings of the prior art led it to improperly discount CSI’s argument in its petition that modifying Uchiyama to place the electrodes outside the lumen would have been a routine design choice. “When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp.” KSR, 550 U.S. at 421. We explained in Uber Technologies, Inc. v. X One, Inc., 1) that when there are a limited number of well-known design choices in the prior art it would have been obvious to substitute one for the other.
Ancora Tech. v. Roku: Nexus of secondary consideration is not negated merely because other patents may also be implicated or because the license arose from settlement
The Federal Circuit affirmed PTAB's prima facie obviousness finding but vacated because objective indicial were mishandles. Specifically, the Board applied an improperly heightened nexus requirement to licenses offered as objective indicia of nonobviousness, requiring reconsideration and reweighing on remand.
Issue/Holding: The nexus standard for patent licenses offered as objective indicia of nonobviousness: For licenses to the challenged patent, the Board may not demand product-style claim-by-claim or feature-parsing nexus showings; licenses are inherently tied to the patented technology, and nexus is not negated merely because other patents may also be implicated or because the license arose from settlement.
Bayer Pharma v. Mylan Pharma: Clinical proof of efficacy does not imply a nexus to the merits of the invention therefor cannot establish nonobviousness
The Federal Circuit held that that Bayer's “unexpected results” theory lacked a nexus because it relied solely on a functionally unrelated limitation (“clinically proven effective”) so secondary considerations did not overcome obviousness.
Shockwave Medical v. Cardiovaacular Sys.: Excitement of potential commercial success is “weak” evidence of objective indicia
The Federal Circuit affirmed obviousness, upholding the Board's findings that Shockwave was not entitled to a presumption of nexus with respect to secondary considerations because its objective indicia evidence did not outweigh evidence of obviousness.
ams-OSRAM USA v. Rensas Electronics America: “Proper accessibility” in Texas
The Federal Circuit reversed Judge Mazzant in the Eastern District of Texas on his holding that a trade secret first became accessible when Intersil successfully reverse-engineered the trade secret from TAOS' product. The court held that:
Under Texas law, information that is generally known or readily available by independent investigation is not secret for purposes of trade secrecy. Information cannot be the subject of a trade secret if it is readily ascertainable without engaging in tortious behavior. The practical focus of the inquiry reflects the need to ensure that a tradesecret remedy is tailored to preventing or negating the unfair advantage derived from improper acquisition. A trade secret becomes “properly accessible” where the secret is embodied in a publicly available product: Under Texas trade-secret principles, information is not secret once it is readily ascertainable by proper means, including straightforward reverse engineering after public release; proper accessibility does not depend on when the misappropriator actually succeeded in reverse engineering.
In Re Riggs: The provisional application relied upon for priority must provide written description support for portions of the reference relied upon for the rejection
The Federal Circuit held that a published application's pre-AIA § 102(e) date can reach back to a provisional only for subject matter in the published application that is actually supported in the provisional, and vacated the Board's decision for lacking that analysis.
Lynk Labs v. Samsung Electronics Co.: Pre-AIA 102(e)(1) reference is prior art as of its filing date, even if published after the challenged patent's priority date
The Federal Circuit affirmed the Board's unpatentability determination in an inter-partes review applying pre-AIA §§ 102/103 prior art rules within the AIA IPR framework.
In particular, the Federal Circuit held that, in an IPR, a published U.S. application qualifies as a prior-art printed publication as of its U.S. filing date by virtue of pre-AIA § 102(e)(1), even if published after the challenged patent's priority date. Because a published patent application is a “printed publication” and pre-AIA § 102(e)(1) accords such applications prior-art effect as of their U.S. filing date, § 311(b)'s “prior art consisting of patents or printed publications” includes published applications with § 102(e)(1) filing-date priority even if publication post-dates the challenged patent’s priority date.
Merck Serono v. Hopewell Pharma Ventures: Pre-AIA § 1-2(a)/(3): “by another” includes overlapping inventors
The Federal Circuit clarified the pre-AIA meaning of “by another” or “by others” under § 102(a)/(e) when a reference and the challenged patent have overlapping inventors. Specifically, the court held that, for joint-inventor patents, a reference disclosure is excluded as not “by another” only if the relied-upon disclosure reflects the work of the same inventive entity as the challenged claims. Any mismatch in inventive entity (whether inventors are added or omitted) makes the disclosure “by another” unless the patentee proves teh disclosure was the joint invention of the later inventive entity.
In addition, the court held that the PTAB did not violate the APA by applying identity of inventive entity rule without additional opportunity for evidence or argument. Stated the court: ”Land controls the legal definition of 'by others' or 'by another' in §§ 102(a), (e). Merck thus cannot claim a lack of knowledge of the rule of law based on some arguably contrary language int he MPEP.”
Patent in suit: 8,167,141
Claim 1: A gravity-fed water filter, comprising:

wherein the filter achieves a Filter Rate and Performance (FRAP) factor of about 350 or less according to the following formula: [metric].
Brita LP v. ITC: Single enabled embodiment is insufficient to meet written description or enablement requirements for a broad functional claim
The Federal Circuit affirmed the ITC's holding that Brita's patent for a gravity-fed filter is invalid for lack of written description, lack of enablement, and indefiniteness. The patent lacked written description support for a functionally-defined genus claim that extended beyond the single disclosed species.
Specifically, the court held that:
Duke Univ. v. Sandoz: Adequate written description of claimed chemical genus/subgenus
The Federal Circuit reversed the lower District of Colorado decision that claim 30 was non invalid. Specifically, the Federal Circuit held that claim 30 lacked adequate written description support for a claimed chemical genus/subgenus because the written description failed to present either a representative number of species within the claimed scope or disclosure of common structural features with enough precision (i.e., sufficient blaze marks) for a skilled artisan to visualize or recognize the claimed members.

In re Riggs: Priority date of prior art reference limited by support in the priority document
The Federal Circuit reversed the PTAB's finding of invalidity based on a § 102(e) prior art reference. To predate the critical date, the Board accorded to the reference a priority date based on the filing date of the provisional application, and cited Dynamic Drinkware for the proposition that so long as a single claim is supported by the priority document (i.e., the provisional application) then all of the content of the application is accorded that priority date.
The Federal Circuit vacated PTAB's assertion that a previously filed patent application qualifies as prior art under Dynamic Drinkware. Stated the court: “to claim priority to the provisional filing date, the portion of the application relied on by the examiner as prior art must be supported by the provisional application.”
Sage Products v. Stewart: Enablement when demonstrated by a second reference.
Here, the Federal Circuit held that enablement of an anticipatory reference may be supported by a second references that demonstrates the claimed subject matter was in the public’s possession or could be practiced by skilled artisans using routine/known techniques; considering additional references to assess the state of the art is permissible and does not necessarily constitute impermissible gap-filling.
Seegan v. Daiichi Sankyo Co.: Broad genus disclosure insufficient to support/enable later-claimed subgenus
The Federal Circuit reversed the Eastern District of Texas' denial of Daiichi's JMOL motion for dismissal of the jury verdict based on the claims being unsupported by sufficient written description and non-enabled. Because the patent relied on a priority date of a previously-filed application to predate the sale of Daiichi's cancer drug, Enhertu, the court commented that “one cannot avoid the suspicion that the '039 patent was filed specifically to encompass Enhertu, which is permissible if it was entitled to a filing date antedating any public disclosure of Enhertu.”
The court held:
In re: Xencor, Inc.: Jepson claim preambles are limiting and must be enabled.
The Federal Circuit upheld the Appeals Review Panel's ruling that § 112 requires that the specification provide support for the admitted prior art preamble to a Jepson claim as well as the novel subject matter recited after the transitional phrase (e.g., “wherein the improvement comprises”).

Mondis Tech. v. LG Electronics: District court reversed on unsupported identifier mapping
The Federal Circuit reversed the District of New Jersey because the amended claim limitation requiring an ID number that identifies at least a type of display unit lacked written-description support in the originally filed specification, which only disclosed one-to-one identification of specific devices and did not reasonably convey possession of type-based identification.
Novartis Pharma. v. Torrent Pharma: Enablement not required as to infringed product
The Federal Circuit reversed the Distr. of Delaware's finding that that the '659 patent was required to describe the full scope of the asserted claims, including the accused complexes sold by Novartis.
Specifically, the Federal Circuit held that § 112 written description requires that the specification reasonably conveys possession of the claimed subject matter; it need not describe unclaimed later-discovered features (such as a complexed form) even if an accused product practicing those features may infringe the properly construed claims.
Akamai Tech. v. MediaPointe: Objective boundaries needed for “optimal” or “best” in claim
Claim 1. A system [. . .] wherein the management center comprising a mapping engine that is configured to map trace routes between the management center, at least one of the nodes, and at least the first client so as to determine one or more optimal routes. . . .“
The Federal Circuit affirmed invalidity where degree terms (“optimal,” “best”) lacked objective boundaries in the intrinsic record, despite reference to trace-route measurements. The court held that terms of degree are indefinite unless the specification/prosecution history supply objective boundaries that allow a skilled artisan to determine scope with reasonable certainty; merely requiring use of trace-route data does not cure indefiniteness where the intrinsic record leaves open-ended which factors apply and how to resolve tradeoffs among metrics that can diverge. A claim’s requirement to use a tool or dataset (here, trace routes) does not provide an objective boundary if it is non-exclusive (other factors may be considered) and does not specify how to choose among multiple potentially conflicting measurement methods or combinations.
Canatext Completion Solutions v. Wellmatics: Antecedent basis error non-fatal
The Federal Circuit reversed an indefiniteness holding based on missing antecedent basis error by concluding the claim contained an obvious error that can be judicially corrected. Because the issue was resolved on intrinsic evidence without fact findings, the court treated the matter as de novo claim interpretation and rejected reliance on expert testimony not supplying extrinsic facts. The court also confirmed that the judicial correction is unavailable if the prosecution history suggests a different interpretation, and found no such prosecution-history indication here.
The court held that it may judicially correct claim language only under a demanding standard: the error must be evident on the face of the patent to a skilled artisan, the correction must not be subject to reasonable debate based on the claims and specification, and the prosecution history must not suggest a different interpretation (and, at least here, the correct is a simple or minor textual change).
Akamai Technologies v. MediaPointe: “Received by a management center” means the “request” is properly limited to an electronic message, not the act of entering a URL into a browser
The Federal Circuit held that the ordinary meaning of an unconstructed limitation still must be a reasonable meaning in context. Here, it was reasonable for a jury to find that “request . . . received by a management center” is limited to a computer message. Even when a limitation is left to ordinary meaning, the factfinder may adopt only meanings that are reasonable in context; language requiring a “request” to be “received by” a management center reasonably denotes a computer message capable of being received, not a user’s generalized “attempt” to access content.
Alnylam Pharmas. v. Moderna: Claim term limited to express definition despite being qualified by “unless otherwise specified” and dependent claim differentiation argument
The Federal Circuit affirmed the Delaware district court's ruling that the specification's “Definitions” section controls the meaning of the claimed term where it appears unless the patent clearly and explicitly says otherwise. Here, the court rejected the logic that, where a dependent claim is presumed to further narrow the asserted independent claim, the defined term must be more broadly construed because the dependent claim, in this case, can still narrow the independent claim in a different way without contradicting the definition.
Apple v. Gesture Techn. Partners: Plain meaning does not import implication
The Federal Circuit affirmed the lower court's interpretation of a dependent claim requiring “a light source for illuminating said object” as not requiring that the light source illuminate the object while the camer means obtains an image of the object. The court held that it will not import an unstated temporal or antecedent-basis limitation into a dependent claim.
Bayer Pharma v. Mylan Pharmas.: Functionally unrelated limitations; “product comprising” two ingredients must be a single dosage form or product containing both ingredients
The Federal Circuit held that adding the limitation “clinically proven effective” cannot confer patentability to an otherwise anticipated or obvious treatment method, making inherent anticipation analysis unnecessary. The court distinguished Allergan Sales v. Sandoz 2) stating that the phrase “clinically proven effective” does not further limit the claimed invention since the claims already specify exact dosages to be administered and therefore the additional limitation “clinically proven effective” does not further define the dosages that are administered.
The Federal Circuit also found that the phrase “a first product comprising rivaroxaban and aspirin” requires a single dosage form/product containing both rivaroxaban and aspirin; construing it to cover separate dosage forms would improperly render “a first product comprising” meaningless and is inconsistent with the specification’s distinction between separate dosage forms and a combination dosage form.
Causam Enterprises v. Ecobee Techs: PTAB's refusal to accept patent owner's proposed construction incorporating temporal component
The Federal Circuit affirmed the Board's construction of a key limitation, rejecting an added restriction not supported by the claim language and disfavored because it would exclude disclosed embodimetns. The court held that claim language requiring data to “correspond” to a power reduction does not, without more, impose a temporal restriction on when the data are generated, and constructions that would exclude disclosed embodiments (e.g., estimates or database-derived values measured before or after an event) are disfavored.
In re Xencor: “Treating a patient” in preamble is limiting because another portion of the preamble is referred from the claim body, and the two preamble portions cannot, in this instance, be split into limiting and non-limiting parts
The Federal Circuit agreed with the ARP that “the preamble term 'treating a patient by' is limiting. First, it is important that Xencor does not dispute that the second part of the preamble, 'administering an anti-C5 antibody,' is limiting. The claim language refers back to this section of the preamble—'wherein said anti-C5 antibody with said amino acid substitutions has increased in vivo half-life as compared to said antibody without said substitutions.' At least one portion of the preamble is therefore limiting. Although we may split a preamble into limiting and non-limiting parts, and have done so in cases such as TomTom, Inc. v. Adolph, 3), the preamble here 'cannot be neatly packaged into two separate portions.' Bio-Rad Lab’ys, Inc. v. 10X Genomics Inc., 4). Here, the phrase 'treating a patient' is directly connected with the word 'by' to the phrase 'administering an anti-C5 antibody.' And given our 'disinclination' to 'splic[e]' a preamble into limiting and non-limiting parts, id. at 1371, this lends credence to the argument that the entire preamble should be considered limiting.”
Merck Serono v. Hopewell Pharma Ventures: Claimed dosing of an amount in mg/kg does not require weight-based dosing steps
The Federal Circuit rejected an implied patient-weight determination limitation when a claim recited a dose expressed in mg/kg amounts. The court held that claims reciting a “total dose reached” expressed in mg/kg do not, without an explicit step, require determining patient weight or performing weight-based dosing calculations; a prior-art disclosure (or infringement) can satisfy the limitation based on the administered dose fitting the claimed range regardless of how that dose was determined.
Regeneron Pharmas. v. Mylan Pharmas.: Becton presumption applies to pharmaceutical formulation claim that separately formulation components
The Federal Circuit affirmed a denial of preliminary injunction based on a substantial question of noninfringement because the accused product lacked separately claimed component under the adopted construction, where separately recited “VEGF antagonist” and “buffer” are presumed to be distinct under Becton.
The court held:
Rex Medical v. Intuitive Surgical: A “beam [that] comprises an upper portion and a lower portion and a web coupled between the upper portion and the lower portion . . . configured to cause the staple pusher to move a staple” does not imply an I-beam shape
Here, the Federal Circuit held that, absent intrinsic evidence clearly narrowing scope, courts should not import limitations from a depicted embodiment to confine a broader claim term (here, “lower portion”) to a specific I-beam substructure when the claim does not require an I-beam.
Shockwave Medical v. Cardiovascular Systems: “Angioplasty balloon,” in the context of a device for pulverizing hardened vascular plaque, does not require that the balloon press plaque into the vessel wall
The Federal Circuit held that absent clear claim language, specification support, or prosecution disclaimer, “angioplasty balloon” is not limited to balloons that displace plaque into the vessel wall; adding “angioplasty” during prosecution without clear narrowing statements does not create a disclaimer of broader scope.
Sierra Wireless v. Sisvel: “Mutually exclusive” conditional language in claims
Claim 1: A method of performing automatic repeat request (ARQ) in a wireless communication system, the method performed by a receiver and comprising:
[a] detecting whether at least one data block to be received from a transmitter is missed;
[b] starting a timer when the at least one data block is detected as missed;
[c] stopping the timer when the at least one data block is received from the transmitter while the timer is running, in order to prevent a triggering of a status report before the timer expires; and
[d] transmitting the status report to the transmitter after the timer expires, wherein the status report comprises a positive acknowledgement indicating receipt of at least one received data block.
The Federal Circuit rejected the Board's reasoning that limitations 1[c] and 1[d] are mutually exclusive and “cannot both occur i response to the same set of stimuli” because the timer either stops . . . or expires.” The court said “that conclusion does not follow from the premise describing the claim language. [. . .] Here, we reject the Board's conclusion because the plain and unambiguous language of claim 1 requires that a method, to come within the claim, must perform both limitations 1[c] and 1[d] where their preconditions apply.” This opinion effectively supersedes the PTAB's precedential ruling in Ex Parte Schulhauser.
The opinion also reinforces procedural rigor at the PTAB: expert testimony on anticipation and obviousness must come from at least a person of ordinary skill in the art as defined by the Board. Because the Board credited testimony from a declarant who lacked the required qualifications without making a specific finding that his experience sufficed, the Federal Circuit vacated the decision for abuse of discretion.

Sigray v. Carl Zeiss X-Ray Microscopy: Magnification of 1X - 10X includes 1
The court held claims anticipated due to inherent disclosure of prior art, finding that the Board improperly and implicitly construed the claimed numeric magnification range (between 1 and 10) to exclude small magnification (that was inherent to the prior art due to non-parallel rays) and held that construction erroneous under the claim's plain meaning. A tribunal engages in claim construction when its reasoning effectively narrows a claim term’s scope (e.g., by requiring divergence “enough” to produce a certain level of magnification); absent intrinsic evidence to the contrary, a numeric range’s plain meaning controls and includes even very small values within the endpoints.
Aortic Innovations v. Edwards Lifesciences: Implied narrowing of term by interchangeable use in specification
Patents in suit:
The Federal Circuit affirmed construing “outer frame: as a “self-expanding frame” based on clear implied lexicography via consistent interchangeable use in the specification. Because the accused device's frame expanded only with the assistance of a balloon, it did not read on the claimed “outer frame.”

FMC v. Sharda USA: Importing a narrowing definition dropped from provisional application is improper
The Federal Circuit reversed the lower court's claim construction that relied on a narrowed interpretation based on a discussion in the provisional application but not in the asserted patent. The court held that when the patentee materially deletes limiting terminology (here, stability-related disclosures) between a provisional application and the issued patent’s specification, those deleted disclosures cannot be used to re-impose the deleted limitation in claim construction; the claim term should receive its plain and ordinary meaning absent other intrinsic support. Although similar claim terms in related patents are often construed consistently, that presumption yields where the patentee materially altered the specification in certain family members in a way that would direct a skilled artisan to understand a different intended meaning.
The court also rejected an attempt by FMC to narrow the claim scope based on a use in the pramble. Preamble language that merely states a purpose or intended use generally is not limiting. Moreover, differences in preamble wording across claims do not make the preamble limiting absent a basis to treat the preamble as claim scope-defining.
HD Silicon Solutions v. Microchip Tech.: Intrinsic evidence controls interpretation of “comprising tungsten” as “elemental tungsten” and not compounds thereof
The Federal Court construed “comprising tungsten” to require elemental tungsten and held the Board's broader construction was incorrect, emphasizing intrinsic evidence over extrinsic evidence. Where the intrinsic record uses explicit compound nomenclature when compounds are intended (e.g., “titanium nitride”) and otherwise discusses a material only as the element with element-specific properties, “comprising [element]” is properly construed to require the elemental form (allowing incidental impurities) rather than encompassing compounds of that element. Extrinsic evidence (including other patents/publications) may assist understanding but cannot be used to vary or expand a claim meaning that is indicated by the patent’s claims/specification/prosecution history.
Iqris Techs. v. Point Blank Enterprises: Discussion of prior art is not clear and unequivocal disavowal
The Federal Circuit held that the district court improperly imported limitations into the term “pull cord,” rejecting a construction requiring direct pulling by a user and excluding cords with handles. The court held that, absent claim language or clear intrinsic evidence of lexicography/disavowal, a court may not limit “pull cord” to cords directly pulled by a user merely because the specification’s preferred embodiments depict direct pulling or use different labels for other cords.
Lynk Labs v. Samsung Electronics Co.: Intrinsic evidence shows “match” not limited to numerical equivalence
The Federal Circuit construed the claim term “matches” to mean “equal to or less than,” rather than strict equivalence, because the intrinsic evidence consistently describes “matching” in functional, tolerance-based terms rather than exact numerical identity. Reading the claim language in light of the specification as a whole, the court explained that the invention is concerned with avoiding over-driving LEDs, which is satisfied when the rectified input voltage does not exceed the aggregate forward voltage of the LEDs. Nothing in the intrinsic record limits “matches” to exact equality, and multiple passages expressly contemplate a “less than or equal to” relationship, making a broader construction not only reasonable but required.
The court relied on precedents for the following principles:
Azurity Pharmas v. Alkem Labs.: Adding “consisting of” to avoid prior art is a clear and unmistakable disclaimer
The Federal Circuit held that Azurity clearly and unmistakably surrendered claim scope covering any presence of propylene glycol by inserting “consisting of” the list of ingredients to avoid prior art wherein propylene glycol was used as a stabilizer, even though th list of ingredients included a flavoring agent. Because the accused device included a flavoring agent containing propylene glycol it was non-infringing.
The court held:
Barrette Outdoor Living v. Fortress Iron: criticism in spec of prior art feature does not justify construing claims as avoiding that feature
The Federal Circuit affirmed noninfringement based broadly construing “boss” not necessarily fastener-less, despite the patent's discussion of multiple advantages of fastener-less bosses. The court held that a patent's discussion of multiple advantages does not justify importing one advantage-related feature into claims absent absent clear and unmistakable disclaimer; here, criticism of fastener-based prior art did not clearly limit “boss” to fastener-less structures.
Eye Therapies v. Slayback Pharma: “Consisting essentially of” narrowed by prosecution disclaimer
The Federal Circuit relied on prosecution history statements accompanying an amendment define the scope of “consisting essentially of,” treating explanatory remarks and definitional “i.e.” usage as limiting. The court held that although “consisting essentially of” is typically semi-open, the intrinsic record can assign it an atypically restrictive meaning; here, the prosecution history establishes that the phrase excludes use of active ingredients other than brimonidine in the claimed methods. When the applicant uses “i.e.” to equate a claim phrase with a particular meaning in prosecution arguments, that usage is strongly definitional and supports construing the claim phrase consistently with the stated definition. Where claims were narrowed during prosecution, claims need not cover every described embodiment.
Focus Products Group Internat'l v. Kartri Sales Co.: Election of species without objection is disclaimer of non-elected species
The Federal Circuit reversed the District Court for the Southern District of NY based on corrected claim scope for a shower curtain “ring.” The court held that prosecution history including restriction and an election to withdraw nonelected species, and prosecution of a divisional application excluding the elected species can constitute clear and unmistakable disclaimer of the claim scope. Here, because the properly construed claims exclude a feature present in the accused product (i.e., rings with flat upper edges) summary judgment of infringement cannot stand and must be reversed as to the party preserving the noninfringement issue.
Maquet Cardiovascular v. Abiomed: Related applicant's prosecution history is relevant only when the earlier prosecution addresses a limitation in common with the claim term being construed
The Federal reversed and remanded to the district court's claim construction claims with added negative limitations. The court held that prosecution disclaimer from a related patent's prosecution is relevant only when the earlier prosecution addresses a limitation in common with the claim term being construed; material differences in claim language (e.g., claiming an “entire elongate lumen distal to” a component versus a “guide mechanism comprising a lumen”) defeat reliance on that history to import a negative limitation.
Restem v. Jadi Cell: Applicant's acquiescence to Examiner's repeated characterization constituted disavowal
The Federal Circuit held that clear examiner statements characterizing the allowed claim scope, coupled with applicant acquiescence during prosecution, can narrow claim scope (here, to a “cell population”), and that narrowed understanding may control over broader specification disclosures/definitions.
Fintiv v. PayPal Holdings: “handler” is a nonce term
The Federal Circuit held that the district court correctly analogized “handler” with the nonce term, “module” which was previously determined to be a generic description of software or hardware that performs a specified function. The prefix “payment” (for “payment handler”) did not impart structure and merely describes the function of the handler: to perform payment functions. The Federal Circuit further agreed with the district court that the specifications of the asserted patents do not disclose any algorithm to perform the recited function, and held the payment-handler terms indefinite.

Optis Cellular Technology v. Apple: District court's reasoning that “selecting unit” does not invoke § 112 ¶ 6 failed to explain how the selecting unit operates
The Federal Circuit held that “selecting unit” invoked § 112 ¶ 6 and remanded for the corresponding structure and indefiniteness analysis. More specifically, the court found that a “unit” term modified only by functional language (e.g., “selecting”/“configured to randomly select”) is a nonce term that fails to connote sufficiently definite structure and therefore invokes § 112 ¶ 6; remand is appropriate for the district court to determine whether the specification discloses adequate corresponding structure (and resulting definiteness).
Steuben Foods v. Shibuya Hoppmann: District court's JMOL reversed; infringement found under § 112 ¶ 6 “equivalents” standard
The Federal Circuit reversed the district court's JMOL of noninfringement for a § 112 ¶ 6 “means for filling” limitation where substantial evidence supported that accused structures were equivalent in the context of the claimed function. For a § 112 ¶ 6 limitation, structural differences must be assessed in the context of the claimed function and the overall corresponding structure; substantial evidence can support equivalence where accused components perform the identical function in substantially the same way with substantially the same result, even if component-level details differ.
IGT v. Zynga: Decision not to apply interference estoppel as a bar to institution is nonappealable
The Federal Circuit held that the PTO's decision not to apply interference estoppel as a bar to institution is a nonappealable institution determination under 35 U.S.C. § 314(d), with no Cuozzo “shenanigans” exception on these facts. The court also rejected a procedural challenge that the Board relied on a new, unargued unpatentability theory, finding adequate notice and opportunity to respond under IPR due-process/APA principles.
The court held that:

In an obviousness analysis, the Board must consider all properly presented evidence of secondary considerations (including copying) and assign it whatever weight the evidence warrants; it is reversible error to omit discussion of such evidence on the ground that the Board is not positioned to evaluate the broader litigation record.
