Justia Patents Opinion Summaries

Serta filed a patent infringement action against Casper, citing the 173, 763, and 935 patents. Those patents cover mattresses that include a channel and methods for forming it. These mattresses can have varying areas of firmness by inserting reinforcement of various types into their channels that can be located at regions where additional support is desired. Casper filed three motions for summary judgment directed to non-infringement of Casper’s accused mattresses, accused methods of manufacturing, and redesigned mattresses. While Casper’s summary judgment motions were pending, the parties executed a settlement agreement and advised the district court of the settlement. The district court nevertheless granted Casper’s summary judgment motions of non-infringement. It later denied Serta’s motions to vacate the summary judgment order and to enforce the settlement agreement. The Federal Circuit vacated and remanded with instructions to enforce the settlement agreement. There is no contention that the settlement or the relief sought by Serta is unlawful or contrary to public policy. There is also no dispute that the parties executed the agreement before the district court issued the summary judgment order; Casper has admitted that the agreement was binding. The settlement agreement mooted the case even though it included terms that required future performance. View "Serta Simmons Bedding, LLC v. Casper Sleep Inc." on Justia Law

Acoustic’s 841 patent relates to communications systems for utility providers to remotely monitor groups of utility meters, e.g., electricity meters. According to Acoustic, the claimed invention was “an improvement upon prior art automated meter reading systems that used expensive and problematic radio frequency (RF) transmitters, or systems that relied on human meter-readers using hand-held or vehicle-mounted short-range wireless devices to obtain meter readings when they were in a customer’s vicinity.” On Network’s petition, the Patent Trial and Appeal Board instituted inter partes review (IPR). Nine days after institution, Network agreed to merge with Itron, an entity undisputedly time-barred under 35 U.S.C. 315(b). Network and Itron completed the merger during the IPR proceeding. The Board later issued a final written decision and found the challenged claim unpatentable. The Federal Circuit affirmed, rejecting Acoustic’s claim that the inter partes review was time-barred due to Network’s and Itron’s merger-related activities. Acoustic waived its time-bar argument because it failed to present that argument before the Board. Substantial evidence supports the Board’s unpatentability findings based on anticipation.

Andrea sued Apple for infringement of Andrea’s 345 patent, relating to certain aspects of digital audio processing. Apple filed two inter partes review (IPR) petitions. The Patent Trial and Appeal Board instituted review. In its 626 IPR Final Written Decision, the Board concluded that, in light of prior art, several challenged claims were unpatentable. The Board declined to consider certain arguments in Apple’s reply brief because Apple was raising new arguments in its reply brief. In its 627 Decision, the Board concluded that, in light of other cited art, several challenged claims are unpatentable. The Board construed the term “periodically” in favor of Andrea. Between the two IPRs, the Board held that all challenged claims except claims 6–9 are unpatentable.The Federal Circuit vacated with respect to the 626 IPR; the Board erred in refusing to consider Apple’s reply arguments. Apple’s reply does not cite any new evidence or “unidentified portions” of the reference at issue but merely demonstrates another example of the same algorithm to further explain why the reference discloses the “current minimum” and “future minimum” limitations of claims 6–9. Apple’s reply arguments are responsive to arguments raised in Andrea’s Patent Owner Response. The petitioner in an IPR may introduce new evidence after the petition stage if the evidence is a legitimate reply to evidence introduced by the patent owner. The court affirmed with respect to the 627 IPR, finding the decision supported by substantial evidence. View "Apple Inc. v. Andrea Electronics Corp." on Justia Law

Cheetah’s 836 patent is directed to optical communication networks. AT&T uses hardware and software components in its fiber-optic communication networks. Cheetah asserted that AT&T infringes the 836 patent by making, using, offering for sale, selling, or importing its fiber equipment and services. Ciena was allowed to intervene in the suit because it manufactures and supplies components for AT&T’s fiber-optic systems; those components formed the basis of some of Cheetah’s infringement allegations. Ciena and AT&T then moved for summary judgment that Cheetah’s infringement claim was barred by agreements settling previous litigation. Cheetah had sued Ciena and Fujitsu and executed two license agreements—one with Ciena and one with Fujitsu. Ciena and AT&T argued that the licenses included implicit licenses to the 836 patent covering all of the accused products. The district court dismissed the suit. The Federal Circuit affirmed, rejecting Cheetah’s argument that the parties did not intend that the licenses extend to the 836 patent. The court noted the presumption that a license to a patent includes a license to its continuation. The naming of certain patents expressly does not evince a clear mutual intent to exclude other patents falling within the general definitions in an agreement. That is especially true here where the licenses list broad categories of patents without reciting their numbers individually. View "Cheetah Omni LLC v. AT&T Services, Inc." on Justia Law

HVO’s 941 and 488 patents share a specification and are directed to methods and devices for controlling an oxygen generating system, which is used to sustain and manage airflow for torch glass artists who use surface mix glass torches. HVO sued Oxygen Frog for infringement. A jury concluded that claims 1 and 7 of both patents, the only claims tried, would have been obvious under 35 U.S.C. 103. The Federal Circuit reversed. The district court abused its discretion by admitting lay witness testimony regarding obviousness. That testimony, which was directed to the conclusion of obviousness and its underlying technical questions, is the province of qualified experts, not lay witnesses. Admission of that testimony substantially prejudiced the outcome of the case. View "HVLPO2, LLC v. Oxygen Frog, LLC" on Justia Law

Prisua’s patent, entitled “Video Enabled Digital Devices for Embedding User Data in Interactive Applications,” is directed to “generating an edited video data stream from an original video stream” by “substituting at least one object . . . in said original video stream by at least a different object.” The claims at issue are directed to methods and apparatuses for “generating a displayable edited video data stream from an original video data stream.” The Patent Trial and Appeal Board instituted inter partes review (IPR) and held that claim 11 was unpatentable for obviousness but declined to analyze whether other challenged claims were unpatentable as anticipated or obvious, finding those claims indefinite.The Federal Circuit affirmed in part. The IPR statute does not authorize the Board to cancel challenged claims for indefiniteness. The scope of IPR is found in section 311(b), Chapter 31 of Title 35. The scope of post-grant review is in section 321(b), Chapter 32. The use of the word “patentability” in the final written decision provision of each chapter refers to the previously defined scope of the particular review in question. Patentability under section 318(a) refers to the limited grounds of unpatentability described in section 311(b); patentability under section 328(a) refers to the broader grounds of unpatentability described in section 321(b). Reversing in part, the court rejected the Board’s conclusion that the term “digital processing unit” invoked means-plus-function claiming, and that for that reason the remaining claims could not be analyzed for anticipation or obviousness.

Koninklijke's patent identifies prior art technologies for delivering digital content for playback on a client device: downloading and streaming. It states that downloading suffers from delay because the user cannot playback the digital content until after the entire file finishes downloading; streaming generally requires “two-way intelligence” and a “high level of integration between client and server software,” which “mostly excludes third parties from developing custom server software.” On Google’s petition, the Patent Board instituted inter partes review (IPR) and construed the claim term “a given segment of [a/the] media presentation” to mean “a media presentation with multiple segments.” The Board concluded that Google had not demonstrated that any of the claims were anticipated but that Google had demonstrated that claims 1–11 would have been obvious. The Federal Circuit affirmed, first holding that the Board erred by instituting IPR of claims 1–11 based on obviousness over two prior references because Google did not advance such a combination of references in its petition. The Board did not violate 35 U.S.C. 311(b) or the IPR statute in determining that the claims would have been obvious over a prior reference in light of the general knowledge of a skilled artisan. The Board’s factual findings underlying its obviousness determination are supported by substantial evidence. View "Koninklijke Philips N.V. v. Google, LLC" on Justia Law

ARM’s 320 patent describes an adaptor for use with Keurig® single-brew coffee machines or similar brewers, configured to effect operative compatibility between a single-serve beverage brewer [for use with cup-shaped cartridges] and beverage pods. ARM filed an International Trade Court (ITC) complaint against Eko and others. In proceedings involving others, the ITC found that several claims of the 320 patent were invalid for lack of written description. The Federal Circuit affirmed. The ITC made no invalidity determination concerning claims 8 and 19. Eko defaulted in the ITC with respect to ARM’s allegations that it infringed claims 8 and 19. The ITC issued a limited exclusion order and cease and desist order. Eko filed suit in the district court, seeking a declaratory judgment of noninfringement as to claims 8 and 19 and that the claims were invalid as obvious. Eko also asserted infringement of Eko’s 855 patent, which describes a reusable filter cartridge device for single-serve beverage brewing machines. The district court issued a Markman ruling construing various claim terms and granted Eko declaratory judgment of noninfringement. A jury found claims 8 and 19 of the 320 patent invalid as obvious. The court awarded Eko attorney’s fees associated with those judgments. The Federal Circuit affirmed the judgment of invalidity as to the 320 patent, the fee award, and the judgment of infringement as to the 855 patent. View "Eko Brands, LLC v. Adrian Rivera Maynez Enterprises, Inc." on Justia Law

Genentech’s patent is directed to methods of purifying antibodies and other proteins containing a CH2/CH3 region from impurities by protein A affinity chromatography. Protein A affinity chromatography is a standard purification technique employed in the processing of therapeutic proteins, especially antibodies, which involves “using protein A . . . immobilized on a solid phase.” The Patent Trial and Appeal Board instituted inter partes review (IPR) and determined that all the challenged claims were unpatentable as anticipated or obvious in light of prior art references. The Federal Circuit affirmed, finding substantial evidence in support of the findings. The court also rejected Genentech’s argument that retroactive application of IPR to a patent issued prior to the passage of the America Invents Act violates the Fifth Amendment’s Takings Clause; pre-AIA patents were issued subject to both district court and Patent Office validity proceedings. Though IPR differs from district court and pre-AIA Patent Office reexamination proceedings, those differences are not sufficiently substantive or significant such that a “constitutional issue” is created when IPR is applied to pre-AIA patents.

Audio’s patent describes a system for organizing audio files, by subject matter, into “program segments.” ’The system arranges the segments through a “session schedule” and allows a user to navigate through the schedule in various ways. Audio sued CBS, alleging infringement. Later that year, a third party sought inter partes review (IPR) of the patent under 35 U.S.C. 311–319. The Patent Trial and Appeal Board instituted review but the district court case proceeded to trial, with the issues limited to infringement and invalidity of claims 31–34. A jury found that CBS had infringed claims 31–34 and failed to establish by clear and convincing evidence that those claims were invalid. The jury awarded Audio $1,300,000. The Board issued a final written decision in the IPR, concluding that claims 31–35 are unpatentable. The district court stayed entry of its judgment until completion of direct review of the Board’s decision. The Federal Circuit affirmed the Board’s decision. The district court then entered a judgment in favor of CBS. The Federal Circuit affirmed, rejecting Audio’s argument that the courts lacked jurisdiction. To the extent that Audio challenged the district court’s determination of the consequences of the affirmed final written decision for the proper disposition of this case, Audio conceded that governing precedent required judgment for CBS.
