Justia Patents Opinion Summaries

The case involves Gesture Technology Partners, LLC, which owns U.S. Patent No. 7,933,431 related to methods and apparatus for rapid TV camera and computer-based sensing of objects and human input, usable in devices such as handhelds, cars, and video games. After Samsung Electronics requested an ex parte reexamination of the patent, the United States Patent and Trademark Office initiated proceedings. Concurrently, two inter partes review (IPR) proceedings were filed against the same patent by Unified Patents LLC and other entities, resulting in the Patent Trial and Appeal Board invalidating most claims of the patent.After the Patent Trial and Appeal Board issued final written decisions in both IPRs, Gesture Technology Partners petitioned the Patent Office to terminate the ex parte reexamination, arguing that Samsung, as a party to the IPR, was estopped under 35 U.S.C. § 315(e)(1) from maintaining further proceedings on grounds that could have been raised in the IPRs. The Patent Office denied the petition, holding that the estoppel provision did not apply to ongoing ex parte reexaminations. Subsequently, the Board affirmed the examiner’s rejection of claims 11 and 13 as anticipated by a prior patent, Liebermann. Gesture appealed these decisions.The United States Court of Appeals for the Federal Circuit reviewed the case. It held that the estoppel provision of 35 U.S.C. § 315(e)(1) does not apply to ongoing ex parte reexamination proceedings, as the requester does not “maintain” the proceeding—the Patent Office does. The court also affirmed the Board’s finding that the Liebermann patent anticipates claims 11 and 13. Furthermore, it rejected the argument that the Board lacked jurisdiction because the patent had expired, citing continued rights to past damages. The court affirmed the Board’s decision as to claims 11 and 13 and dismissed the appeal as to the previously invalidated claims. View "In Re GESTURE TECHNOLOGY PARTNERS, LLC " on Justia Law

Akamai Technologies, Inc. filed suit in the United States District Court for the Central District of California seeking a declaratory judgment of noninfringement regarding two patents owned by AMHC, Inc. and its subsidiary, MediaPointe, Inc. These patents describe systems and methods for efficiently routing streamed media content over the Internet using an “intelligent distribution network.” After Akamai initiated litigation, MediaPointe counterclaimed for infringement, and Akamai further sought a declaratory judgment of invalidity.During claim construction, the district court issued an order finding that certain claims containing the terms “optimal” and “best” were invalid for indefiniteness. For the remaining asserted claims, the district court granted Akamai summary judgment of noninfringement. The court excluded key portions of MediaPointe’s expert testimony as untimely, and also found that, even considering that testimony, MediaPointe’s evidence did not create a genuine dispute regarding infringement. Specifically, the court determined that the accused Akamai system did not meet the required limitation of “receiving an initial request for media content” as understood in the context of the patents.The United States Court of Appeals for the Federal Circuit reviewed the case and affirmed both the invalidity and noninfringement judgments. The court held that the “optimal” and “best” claim terms were indefinite because the intrinsic record failed to provide objective boundaries for determining what is “optimal” or “best.” The court also concluded that, even with the excluded expert testimony included, MediaPointe had not presented sufficient evidence to create a genuine dispute of material fact regarding infringement. The Federal Circuit affirmed the district court’s judgment. View "AKAMAI TECHNOLOGIES, INC. v. MEDIAPOINTE, INC. " on Justia Law

EscapeX IP, LLC brought a patent infringement suit against Google LLC, alleging that Google’s YouTube Music product infringed its ’113 patent. After Google responded, pointing out factual deficiencies in EscapeX’s claims and highlighting that the accused features either did not exist or predated the patent, EscapeX amended its complaint to target a different Google product. Google repeatedly notified EscapeX that its claims were baseless and requested dismissal, but EscapeX did not respond. The case was transferred from the Western District of Texas to the Northern District of California. Meanwhile, a separate court found all claims of the ’113 patent ineligible under 35 U.S.C. § 101, which EscapeX did not appeal.Upon transfer, EscapeX attempted to file a joint stipulation of dismissal without Google’s consent, misstating that both parties would bear their own fees. Google demanded withdrawal, and a corrected stipulation was later filed. Google moved for attorneys’ fees under 35 U.S.C. § 285, arguing EscapeX’s claims were frivolous and that EscapeX had unreasonably prolonged litigation. The United States District Court for the Northern District of California found Google to be the prevailing party, determined EscapeX’s case was exceptional due to its lack of adequate pre-suit investigation and frivolous claims, and awarded Google attorneys’ fees and costs. EscapeX then moved to amend the judgment under Rule 59(e), presenting new declarations as “new evidence,” but the district court denied the motion, finding the evidence was not newly discovered.Google sought additional attorneys’ fees under 28 U.S.C. § 1927 for costs incurred opposing EscapeX’s Rule 59(e) motion. The district court found EscapeX’s motion frivolous and sanctioned EscapeX and its attorneys jointly and severally. On appeal, the United States Court of Appeals for the Federal Circuit affirmed all of the district court’s orders. The main holdings were that the case was exceptional under § 285, supporting an award of attorneys’ fees, and that sanctions under § 1927 for frivolous litigation conduct were appropriate.

Duke University and Allergan Sales, LLC own a patent relating to methods for treating hair loss using certain prostaglandin F (PGF) analogs. The patent describes a method of growing hair by topically applying a composition containing a PGF analog with specific structural features. Allergan markets Latisse®, a product containing bimatoprost, a PGF analog, for eyelash hair growth. Sandoz manufactures a generic version of Latisse®. Allergan sued Sandoz for patent infringement, specifically asserting claim 30 of the patent, which covers a subgenus of PGF analogs with defined chemical characteristics.In the United States District Court for the District of Colorado, Sandoz stipulated to infringement but challenged the validity of claim 30, arguing it lacked adequate written description, was obvious, and not enabled. After a jury trial, the jury found in favor of Allergan on all grounds, concluding Sandoz had not proven invalidity and awarding damages. Sandoz moved for judgment as a matter of law and for a new trial, both of which the district court denied. Sandoz then appealed.The United States Court of Appeals for the Federal Circuit reviewed the district court’s denial of judgment as a matter of law de novo, applying Tenth Circuit standards. The Federal Circuit held that no reasonable jury could have found that claim 30 was adequately described in the patent specification. The court found that the specification broadly described billions of compounds, while claim 30 covered a much narrower subgenus, and the patent failed to provide sufficient guidance (“blaze marks”) to direct a skilled artisan to the claimed compounds. The court concluded that the written description requirement of 35 U.S.C. § 112(a) was not met and reversed the district court’s judgment, holding claim 30 invalid for lack of adequate written description.

This case concerns a dispute between two companies over alleged infringement of two patents related to illuminated school bus signs. The plaintiff, Smartrend Manufacturing Group (SMG), Inc., claimed that Opti-Luxx Inc. infringed both a design patent (D930) and a utility patent (’491) with its single-piece illuminated school bus sign, which features a rigid plastic housing, an LED light board, and a yellow lens with black lettering. The design patent describes certain features as “transparent,” while the utility patent claims a sign with a “frame” that is separate from the sign panel.The United States District Court for the Western District of Michigan held a jury trial, where the jury found that Opti-Luxx infringed both patents. The district court denied Opti-Luxx’s motion for judgment as a matter of law (JMOL) and issued a permanent injunction against Opti-Luxx. The court construed the term “transparency” in the design patent to mean both “transparent” and “translucent,” and determined that the “frame” in the utility patent must be a separate and distinct component. The trial on the utility patent proceeded under the doctrine of equivalents, as the accused product did not literally have a separate frame.On appeal, the United States Court of Appeals for the Federal Circuit found that Opti-Luxx had forfeited its objection to the plaintiff’s expert testimony regarding the design patent. However, the appellate court held that the district court erred in construing “transparency” to include “translucent,” and ordered a new trial on infringement of the design patent. Regarding the utility patent, the appellate court concluded that no reasonable jury could have found infringement under the doctrine of equivalents, as the accused product did not perform the required functions of a separate frame. The Federal Circuit reversed the judgment of infringement for the utility patent, vacated the judgment and injunction for the design patent, and remanded for further proceedings.

A company developed a specialized vehicle-mounted stairway, with design work primarily performed by the founder’s son, who was promised equity in the business but never received it due to the majority owner’s repeated refusals. The son, with his father’s assistance, eventually obtained a patent for the design, which he used as leverage to seek compensation. Negotiations between the parties failed, leading to the father’s removal as company president and the company filing suit against both the father and son. The company alleged breach of fiduciary duty, misappropriation of trade secrets, business conspiracy, unjust enrichment, fraud, and breach of contract, while the son counterclaimed for patent infringement.The United States District Court for the Eastern District of Virginia granted summary judgment to the father and son on all claims except a breach of contract claim against the father and the son’s patent counterclaim. The court found most claims time-barred or unsupported by evidence, and later, the company voluntarily dismissed its remaining claim. The son’s patent was invalidated by a jury. The district court also awarded attorneys’ fees and costs to the father as the prevailing party under the company’s operating agreement.The United States Court of Appeals for the Fourth Circuit reviewed the case de novo and affirmed the district court’s rulings. The appellate court held that the company’s claims were either time-barred under the applicable statutes of limitations or failed on the merits, as there was no evidence the son benefited from the patent or that he had signed a non-disclosure agreement. The court also affirmed the award of attorneys’ fees and costs to the father, finding no error in the district court’s application of Delaware law or its determination of the prevailing party.

Canatex Completion Solutions, Inc. owns a patent for a “releasable connection” device used in oil and gas wells, which consists of two parts that can be disconnected downhole if necessary. Canatex alleged that several companies infringed its patent, specifically claims 1, 4–13, and 15–19. The dispute centered on the claim language “the connection profile of the second part,” which appears in the independent claims and the specification. Canatex argued that this was a clerical error and that a person skilled in the art would recognize the intended meaning as “the connection profile of the first part,” since only the first part’s connection profile is described and depicted in the patent.The United States District Court for the Southern District of Texas reviewed the case. During claim construction, the defendants argued that the claims were indefinite due to the lack of an antecedent basis for the disputed phrase. The district court agreed, finding the error was not evident from the face of the patent and that the correction was not as simple as Canatex suggested. The court held all asserted claims invalid for indefiniteness and entered final judgment based on a joint stipulation.On appeal, the United States Court of Appeals for the Federal Circuit reviewed the district court’s claim construction de novo. The appellate court held that the error in the claim language was evident on the face of the patent and that the only reasonable correction, based on the intrinsic evidence, was to change “second” to “first.” The Federal Circuit reversed the district court’s judgment, ruling that judicial correction of the claim was appropriate under the demanding standard for such corrections, and remanded the case for further proceedings consistent with the corrected claims.

The case concerns the validity of certain claims in two patents owned by a pharmaceutical company, which relate to methods of treating multiple sclerosis (MS) using oral administration of cladribine according to a specific dosing regimen. Before the patents’ priority date, cladribine was already known as a treatment for MS, but was typically administered intravenously or subcutaneously due to safety concerns. The patent owner, in partnership with another company, developed an oral formulation and dosing schedule for cladribine. During this collaboration, confidential information was exchanged, and a third party later filed a patent application (the Bodor reference) disclosing a similar dosing regimen. Another prior publication (Stelmasiak) described different cladribine regimens for MS.The Patent Trial and Appeal Board (PTAB) reviewed two inter partes review petitions challenging the patents’ claims as obvious over the combination of the Bodor and Stelmasiak references. The Board determined that the Bodor reference qualified as prior art, finding no complete overlap in inventors between the patents and the reference, and concluded that the patent owner failed to show that all named inventors of the patents contributed to the relevant disclosure in Bodor. The Board also found that the combination of Bodor and Stelmasiak rendered all challenged claims obvious, and rejected arguments that the claims required weight-based dosing or that the prior art failed to teach the claimed regimen.On appeal, the United States Court of Appeals for the Federal Circuit affirmed the Board’s decisions. The court clarified that, under pre-AIA law, a reference is “by another” and thus prior art unless the inventive entity is identical to that of the challenged patent. The court held that the Board did not err in its legal analysis, factual findings, or claim construction, and that substantial evidence supported the Board’s obviousness determination. The Board’s unpatentability findings were affirmed. View "MERCK SERONO S.A. v. HOPEWELL PHARMA VENTURES, INC. " on Justia Law

Aortic Innovations LLC owns four related patents concerning devices used in transcatheter aortic valve replacement, a procedure for treating diseased aortic valves. The patents share a common specification and claim priority to the same provisional applications. The claims focus on a transcatheter valve assembly featuring an “outer frame” and an “inner frame.” Aortic alleged that Edwards Lifesciences’ SAPIEN 3 Ultra valve, which uses a single balloon-expandable frame, infringed these patents.The United States District Court for the District of Delaware presided over the initial litigation. Edwards Lifesciences petitioned for inter partes review before the Patent Trial and Appeal Board, which instituted review for three of the patents but not the ’735 patent. The district court stayed the case except for the ’735 patent. During claim construction, the parties disputed the meaning of “outer frame.” The district court found that the patentee had acted as their own lexicographer, redefining “outer frame” to mean “a self-expanding frame.” The court applied this construction to all asserted patents and, following a joint stipulation, entered judgment of non-infringement because Edwards’ accused product did not have a self-expanding frame.On appeal, the United States Court of Appeals for the Federal Circuit reviewed the district court’s claim construction de novo. The Federal Circuit agreed with the district court’s construction, holding that the specification consistently and interchangeably used “outer frame” and “self-expanding frame,” thereby redefining the term. The court affirmed the judgment of non-infringement for three patents and dismissed the appeal as to the fourth patent (’538) for lack of jurisdiction, as its claims had been cancelled by the Patent Office. The Federal Circuit also found that Aortic’s judicial estoppel argument was forfeited. View "AORTIC INNOVATIONS LLC v. EDWARDS LIFESCIENCES CORPORATION " on Justia Law

Centripetal Networks LLC owns a patent related to rule-based network threat detection for encrypted communications. In November 2021, Palo Alto Networks petitioned for inter partes review (IPR) of certain claims of Centripetal’s patent. The Patent Trial and Appeal Board (PTAB) instituted the IPR with a panel of three administrative patent judges (APJs). Subsequently, Cisco Systems and Keysight Technologies filed similar petitions and sought to join the proceedings. During the process, Centripetal discovered that one APJ, McNamara, owned Cisco stock and moved for the recusal of the panel and vacatur of the institution decision, arguing a conflict of interest. After rehearing requests and additional disclosures, APJ McNamara and another APJ withdrew from the panel, but the Board denied Centripetal’s recusal motion as untimely and found no violation of ethics rules or due process.The PTAB, in its final written decision, held claims 1, 24, and 25 of Centripetal’s patent unpatentable as obvious. Centripetal appealed to the United States Court of Appeals for the Federal Circuit, challenging both the merits of the Board’s obviousness determination and the handling of the recusal issue. The Federal Circuit reviewed the Board’s recusal analysis for abuse of discretion and its legal conclusions de novo, finding that Centripetal’s recusal motion was untimely and that the APJ’s stock ownership did not violate applicable ethics regulations. The court also determined that Centripetal’s due process rights were not infringed and that the Board’s actions did not warrant vacatur based on recusal concerns.However, the Federal Circuit found that the PTAB failed to adequately consider evidence of copying presented by Centripetal as part of the obviousness analysis. The court vacated the Board’s final written decision and remanded the case for further proceedings, instructing the Board to properly address the evidence of copying. The disposition by the Federal Circuit was “vacated and remanded.” View "CENTRIPETAL NETWORKS, LLC v. PALO ALTO NETWORKS, INC. " on Justia Law
