Justia Patents Opinion Summaries

This case involves a dispute over several patents relating to digital communication systems that use non-uniform constellations to increase data transmission capacity compared to traditional, uniform constellations operating within similar signal-to-noise ratio (SNR) bands. The plaintiff, Constellation Designs, LLC, alleged that several LG entities infringed claims from four patents by manufacturing and selling televisions compatible with the ATSC 3.0 standard, specifically protocol A/322, which governs over-the-air television broadcasting. The patents at issue cover two primary types of claims: those that recite methods for optimizing constellations based on parallel decode (PD) capacity (“optimization claims”), and those that recite specific, non-uniform constellations (“constellation claims”).The United States District Court for the Eastern District of Texas granted summary judgment to Constellation on patent eligibility for all asserted claims, finding them directed to a technical solution to a technical problem. At trial, a jury found the asserted claims not invalid, found infringement by LG’s accused televisions, awarded damages, and found willful infringement. LG moved for judgment as a matter of law (JMOL) on non-infringement and no damages, and sought to exclude Constellation’s damages expert, but the district court denied these motions. The court then entered final judgment and ongoing royalties.On appeal, the United States Court of Appeals for the Federal Circuit vacated the summary judgment of eligibility for the optimization claims, holding that these claims were ineligible under 35 U.S.C. § 101 because they were directed to the abstract idea of “optimizing” a constellation for PD capacity without specifying how to achieve this result. The court affirmed the eligibility of the constellation claims, finding them directed to a concrete technological solution. The Federal Circuit also affirmed the denial of JMOL on non-infringement and no damages, and the denial of the motion to exclude Constellation’s damages expert. The case was remanded for further proceedings consistent with these rulings. View "CONSTELLATION DESIGNS, LLC v. LG ELECTRONICS, INC. " on Justia Law

Exelixis, Inc. developed Cabometyx®, a cancer treatment containing cabozantinib (L)-malate. After identifying and characterizing crystalline and amorphous forms of this compound, Exelixis obtained several related patents. MSN Laboratories Private Limited and MSN Pharmaceuticals, Inc. sought FDA approval for a generic version using a specific polymorph of cabozantinib (L)-malate and received their own patent for that form. Exelixis sued MSN in the United States District Court for the District of Delaware, alleging infringement of patents covering crystalline cabozantinib (L)-malate salts (the “Malate Salt Patents”) and a patent directed to pharmaceutical compositions with low levels of a genotoxic impurity (the ’349 patent).The District Court held a bench trial. MSN conceded infringement of the Malate Salt Patents but argued they were invalid for lack of written description under 35 U.S.C. § 112(a). For the ’349 patent, MSN contested both infringement and validity. The District Court found the Malate Salt Patents were not invalid, holding the written description requirement was met because the patents disclosed the chemical structure, formula, and crystalline nature of the claimed salts. The court analogized its analysis to GlaxoSmithKline LLC v. Banner Pharmacaps, Inc. For the ’349 patent, the court found no infringement and no invalidity, concluding that the evidence failed to show the prior art inherently disclosed the “essentially free” impurity limitation.The United States Court of Appeals for the Federal Circuit reviewed the case. It affirmed the District Court’s finding that the asserted claims of the ’439, ’440, and ’015 patents had adequate written description support. Regarding claim 3 of the ’349 patent, the Federal Circuit dismissed MSN’s appeal as moot after Exelixis dropped its cross-appeal and vacated the District Court’s judgment of nonobviousness of that claim. The main holdings were affirmance of written description support for the asserted Malate Salt Patents and dismissal and vacatur regarding claim 3 of the ’349 patent. View "EXELIXIS, INC. v.

T-Mobile and KAIFI settled a patent infringement lawsuit involving claims of U.S. Patent No. 6,922,728, which covers Wi-Fi calling technology. As part of their settlement, T-Mobile agreed to make two payments: one immediate payment and another conditional payment, the latter to be made if any of the asserted patent claims “survived” an ex parte reexamination (EPR) at the United States Patent and Trademark Office. After the Patent Office confirmed the patentability of most of the asserted claims without amendment, T-Mobile refused to make the additional payment, arguing that the claims had not truly “survived” the EPR due to alleged changes in claim scope and supposed inequitable conduct by KAIFI during the reexamination.T-Mobile filed a declaratory judgment action in the United States District Court for the Eastern District of Texas, seeking a determination that it had not breached the settlement agreement by withholding the payment. The district court granted summary judgment for KAIFI, holding that the settlement agreement was clear: a claim “survives the EPR” if the Patent Office confirms its patentability in the Reexamination Certificate. The court found T-Mobile’s arguments about claim scope and inequitable conduct irrelevant to the payment obligation and ordered T-Mobile to make the additional payment.On appeal, the United States Court of Appeals for the Federal Circuit reviewed whether it had subject-matter jurisdiction. The court determined that the dispute centered on the interpretation of a contract governed by Texas law and did not necessarily involve a substantial question of federal patent law. Consequently, the court held that it lacked appellate jurisdiction and transferred the case to the United States Court of Appeals for the Fifth Circuit, which has jurisdiction over appeals from the Eastern District of Texas.

AML IP, LLC brought lawsuits in the United States District Court for the Eastern District of Texas against Bath & Body Works Direct, Inc., The Buckle, Inc., and other entities, alleging infringement of U.S. Patent No. 6,876,979. The patent concerns e-commerce methods using a “bridge computer” to facilitate transactions between service providers. Each defendant moved to dismiss the suit on two grounds: improper venue, arguing the requirements of 28 U.S.C. § 1400(b) were not satisfied, and failure to state a claim, contending the patent’s claims were ineligible under 35 U.S.C. § 101.The district court addressed both grounds. It concluded that AML had not established proper venue, justifying dismissal, and separately determined that the patent claims were ineligible for patenting, also warranting dismissal. The court entered judgment accordingly. AML filed a motion to amend the judgment, arguing the court should have dismissed only for venue and not for ineligibility after finding venue improper. The district court denied the motion, explaining it had discretion to address both grounds given they were briefed together and no alternative venue was suggested for transfer. AML appealed, challenging the district court's decision to dismiss on both grounds.The United States Court of Appeals for the Federal Circuit reviewed the appeal, applying Fifth Circuit law for procedural questions. The court held that the district court did not abuse its discretion in dismissing for both improper venue and patent ineligibility, as venue is a waivable issue and courts may resolve multiple grounds when briefed together. The appellate court also declined to address whether the merits dismissal would have preclusive effect in future cases, noting that such determinations are properly made in subsequent actions. The judgment was affirmed. View "AML IP, LLC v. BATH & BODY WORKS DIRECT, INC." on Justia Law

A company specializing in hybrid electric aircraft technology filed suit in Washington state court against a major aerospace manufacturer and its investment affiliate, alleging misappropriation of trade secrets, breach of contract, and tortious interference, among other state law claims. The plaintiff asserted that the defendant improperly used its confidential information, including by incorporating aspects of the plaintiff’s technology into two patents obtained by the defendant. The plaintiff’s claims involved several theories and more than 30 alleged trade secrets.The aerospace manufacturer responded by counterclaiming for a declaratory judgment that its employees were the sole inventors of one of the patents in question. The case was removed to the United States District Court for the Western District of Washington based on this federal patent law counterclaim, and a second inventorship counterclaim was later added regarding another patent. The district court granted summary judgment in favor of the defendant on both patent inventorship counterclaims. The remainder of the plaintiff’s claims proceeded to a jury, which returned a verdict awarding the plaintiff over $92 million for trade secret misappropriation and tortious interference. However, the district court granted the defendant’s post-trial motion for judgment as a matter of law and conditionally granted a new trial, vacating the jury award.On appeal, the United States Court of Appeals for the Ninth Circuit reversed the district court’s post-trial rulings and remanded the case with instructions for reassignment to a different district judge. In a subsequent petition for rehearing, the defendant argued for the first time that appellate jurisdiction belonged exclusively to the Federal Circuit because the counterclaims were compulsory and arose under patent law. The Ninth Circuit held that the defendant’s counterclaims, though arising under federal patent law, were permissive—not compulsory—because they did not share the same operative facts as the plaintiff’s state law claims; thus, Ninth Circuit jurisdiction was proper. The court also held that the district court appropriately exercised supplemental jurisdiction over the state law claims, as they shared a common nucleus of operative fact with the federal counterclaims. The petition for rehearing was denied. View "ZUNUM AERO, INC. V. THE BOEING COMPANY" on Justia Law

Several inventor-advocacy groups challenged the language used on the cover of patents issued by the United States Patent and Trademark Office (PTO), alleging that it is misleading. Specifically, they contended that the statement granting patent holders the “right to exclude others” is inaccurate following the Supreme Court’s decision in eBay Inc. v. MercExchange, L.L.C., which established that injunctions are no longer automatically granted to patent holders. The plaintiffs, all non-profit organizations supporting inventors, argued that the PTO’s failure to amend this language harms them because they must divert resources to educate their members about the true scope of patent rights.The United States District Court for the Eastern District of Virginia dismissed the case for lack of standing, holding that the plaintiffs had not shown a sufficient risk of future injury resulting from the challenged language. The district court also denied leave to amend the complaint, finding that any amendment would be futile. The plaintiffs appealed this decision.The United States Court of Appeals for the Federal Circuit affirmed the district court’s dismissal. The appellate court held that the organizations failed to demonstrate organizational standing because their alleged injury—diverting resources to educate members—was foreclosed as a basis for standing by the Supreme Court’s decision in Food & Drug Admin. v. Alliance for Hippocratic Medicine. The court also found that the plaintiffs did not establish associational standing, as they did not identify any member facing a real and immediate threat of future injury from the patent cover language. The court concluded that amendment of the complaint would be futile, as the foundational deficiencies in establishing standing could not be remedied by further allegations. The judgment of the district court was therefore affirmed. View "US INVENTOR, INC. v. SQUIRES " on Justia Law

A company holding a patent for electrically controlled spectacles filed a lawsuit against a car manufacturer, alleging patent infringement. The plaintiff, represented by its counsel, sought damages for alleged infringement and included a request for pre-suit damages. The defendant moved to dismiss the complaint for failure to state a claim and for improper venue. In response, the plaintiff requested leave to amend its complaint and filed a proposed amended complaint. The plaintiff had previously entered into several settlement agreements licensing the patent to third parties.At the United States District Court for the Southern District of Texas, the judge dismissed the case with prejudice under Rule 12(b)(6), finding that the plaintiff’s proposed amended complaint was futile because it failed to adequately plead compliance with the patent marking requirements under 35 U.S.C. § 287(a), particularly regarding its licensees. The court denied leave to amend, denied a motion to amend the judgment, awarded attorney fees to the defendant under 35 U.S.C. § 285, and sanctioned plaintiff’s counsel, holding both the plaintiff and counsel jointly and severally liable for the attorney fees.On appeal, the United States Court of Appeals for the Federal Circuit affirmed the district court’s dismissal of the complaint without leave to amend, agreeing that amendment would have been futile due to the failure to plead compliance with § 287(a). The appellate court also affirmed the award of attorney fees, finding no abuse of discretion in the determination that the case was exceptional due to the plaintiff’s unreasonable litigation conduct. The court dismissed the portion of the appeal relating to the sanctions against counsel for lack of jurisdiction, as counsel had not properly or timely appealed on his own behalf and the plaintiff lacked standing to contest those sanctions. Costs were awarded to the defendant. View "VDPP, LLC v. VOLKSWAGEN GROUP OF AMERICA, INC. " on Justia Law

The case involved a dispute over the validity of several claims in a patent owned by a company specializing in audience measurement technology. The patent described methods for capturing and processing images to measure and identify audiences exposed to media content, such as television. The technology used cameras to capture images, reduced their resolution to detect heads and faces, and used higher-resolution images for facial recognition. A competitor challenged the patent by petitioning for inter partes review, arguing that certain claims were obvious in light of prior art, specifically a scientific publication by Ying-li Tian, and other patent documents.The United States Patent and Trademark Office’s Patent Trial and Appeal Board reviewed the petition and instituted a review on several dependent claims after the patent owner disclaimed the independent claims at issue. The Board ultimately found all challenged claims unpatentable as obvious over combinations of prior art, including Tian. The patent owner appealed to the United States Court of Appeals for the Federal Circuit, contesting the Board’s determination that Tian was analogous art and that its teachings rendered the claims obvious.The United States Court of Appeals for the Federal Circuit affirmed the Board’s decision. The court held that substantial evidence supported the Board’s finding that Tian was reasonably pertinent to the problems addressed by the patent, namely image processing and facial detection, and thus constituted analogous art. The court also found that the Board did not err in concluding that the challenged claims were obvious in view of the prior art combinations. The court rejected arguments that the Board violated procedural requirements or misapplied the law regarding the scope of analogous art and obviousness. The judgment of the Board was affirmed.

Dental Monitoring SAS owns a patent concerning a method for acquiring and analyzing dental arch images through the use of a deep learning device. The patented method involves acquiring an image, analyzing it with the deep learning device, determining a value for an image attribute, comparing that attribute with a setpoint, and sending feedback if a new image is needed. Align Technology, Inc. challenged the validity of claims 1–15 of this patent before the United States Patent and Trademark Office’s Patent Trial and Appeal Board (the Board), arguing that these claims were obvious in light of three prior art references, including a U.S. patent application (“Carrier”) that claimed priority to a provisional application filed before the effective date of Dental Monitoring’s patent.The Board reviewed whether Carrier qualified as prior art, a determination that depended on whether Carrier could rely on the filing date of its provisional application. The Board held that, under its own precedential decision in Penumbra Inc. v. RapidPulse, Inc., the requirement that a patent’s claim be supported by the provisional application’s written description did not apply under the America Invents Act (AIA) for prior art purposes. Instead, the Board found that Carrier qualified as prior art as of its provisional filing date because the provisional described the relevant subject matter and met certain procedural requirements. The Board then found all challenged claims unpatentable as obvious.On appeal, the United States Court of Appeals for the Federal Circuit vacated the Board’s decision. The court held that, under AIA § 102(d)(2) and § 119(e), a reference patent or application is entitled to the benefit of an earlier filing date for prior art purposes only if at least one of its published claims is supported by the provisional application’s written description as required by § 112(a). The court remanded the case for the Board to make the necessary factual findings under this legal standard. View "DENTAL MONITORING SAS v. ALIGN TECHNOLOGY, INC. " on Justia Law

Socket Solutions, LLC owns a patent covering an indoor electrical wall outlet cover that allows continued use of the outlet while concealing the outlet’s contact openings. The company alleged that Import Global, LLC’s Neat Socket product infringed claim 19 of this patent. Socket Solutions filed suit in the United States District Court for the Southern District of Florida and sought a preliminary injunction to prevent Import Global from manufacturing, using, selling, or importing the accused product in the United States.A magistrate judge in the district court issued reports and recommendations regarding both claim construction and the preliminary injunction motion. The district court adopted these recommendations, with minor modifications not relevant on appeal, and granted Socket Solutions the preliminary injunction. This order barred Import Global from engaging in activities related to the allegedly infringing product, as well as any products not more than colorably different from it, and from inducing others to do so.The United States Court of Appeals for the Federal Circuit reviewed the district court’s grant of the preliminary injunction. The appellate court found that the district court erred in its construction of the patent claim terms “backplate” and “pin” during its analysis of the likelihood of success on the merits. The Federal Circuit held that “backplate” should be construed as the component forming the cover with the frontplate, such that the maximum thickness of the cover is the distance, at the central portion of the cover, between the frontplate and that component, and that “pin” should be given its plain and ordinary meaning as understood by a skilled artisan. The Federal Circuit vacated the preliminary injunction and remanded the case for further proceedings consistent with its opinion. Costs were awarded to Import Global. View "SOCKET SOLUTIONS, LLC v.
