Justia U.S. Federal Circuit Court of Appeals Opinion Summaries

Bel Power sued, alleging that Monolithic infringes Bel’s patents by selling certain power modules to original equipment manufacturers and other distributors and customers that use the products in their own electronic devices. Monolithic moved to dismiss or transfer for lack of venue under 28 U.S.C. 1406(a), arguing that, as a Delaware corporation, it does not “reside” in the Western District of Texas, that it does not own or lease any property in that district, and that the homes of four full-time remote employees in the Western District identified in the complaint to support venue do not constitute a “regular and established place of business.” Monolithic alternatively moved to transfer to the Northern District of California.The Federal Circuit upheld the denial of both requests. Monolithic viewed maintaining a business presence in the Western District as important, as evidenced by a history of soliciting employment in Austin to support local customers, even if none of its Western District employees were required to reside there. Monolithic provided certain Western District employees with lab equipment or products to be used in or distributed from their homes as part of their responsibilities. The convenience of parties and witnesses and the interests of justice did not weigh in favor of transfer under the multi-factor approach; Monolithic failed to demonstrate that California was clearly more convenient than the Western District.

Merck’s 708 patent describes sitagliptin dihydrogen phosphate (sitagliptin DHP), which belongs to the class of dipeptidyl peptidase-IV (DP-IV) inhibitors that can be used for treating non-insulin-dependent (Type 2) diabetes. Mylan petitioned for inter partes review, arguing that claims 1–3, 17, 19, and 21–23 were anticipated by the Merck-owned 489 publication, and the equivalent 871 patent (collectively, Edmondson) Edmondson is directed to compounds that are DP-IV inhibitors, useful in the treatment or prevention of diseases in which the dipeptidyl peptidase-IV enzyme is involved, such as diabetes and particularly type 2 diabetes. Mylan also argued that claims 1–4, 17, 19, and 21–23 would have been obvious over Edmondson and two additional publications.The Federal Circuit affirmed the Patent and Trademark Office Patent Trial and Appeal Board holding that Mylan failed to show that claims 1–4, 17, 19, and 21–23 were anticipated or would have been obvious over the cited prior art at the time the alleged invention was made. Merck reduced to practice more than what is shown in Edmondson for the claimed subject matter. View "Mylan Pharmaceuticals Inc. v. Merck Sharp & Dohme Corp.," on Justia Law

The Indiana Southwestern Railway Company sought to abandon railway easements, in which the owners had reversionary interests. The Surface Transportation Board (49 U.S.C. 10903) issued a Notice of Interim Trail Use and Abandonment (NITU). Negotiations with potential railbanking sponsors failed. Eventually, the NITU expired, Railway abandoned its easements without entering into a trail use agreement, and the landowners’ fee simple interests became unencumbered by any easements.The landowners sought compensation for an alleged taking arising under the National Trails System Act Amendments of 1983, 16 U.S.C. 1247(d), claiming that the government had permanently taken their property in April 2001, when the NITU became effective. The Claims Court found that the government had taken the property but that the taking lasted only from the date the NITU went into effect until it expired. The Federal Circuit affirmed in part. The landowner’s property was temporarily taken under the Trails Act. The NITU delayed the reversion of the owners’ interests. The Railway would have otherwise relinquished its rights to its right-of-way during the NITU period. The court remanded for a determination as to the compensation and interest to which the owners are entitled. View "Memmer v. United States" on Justia Law

Cooperative’s ’452 patent relates to systems and methods of structuring a peer-to-peer (P2P) dynamic network for distributing large files, namely videos and video games. In prior art systems, video streaming was controlled by content distribution networks (CDNs), where the content was “distributed directly from the CDN server originating the content.” The 452 patent claims methods and systems for a network in which content distribution occurs “outside controlled networks and/or [CDNs],” i.e., outside a “static network of controlled systems,” using dynamic P2P networks comprising “peer nodes,” i.e., nodes consuming the same content contemporaneously, that transmit content directly to each other instead of receiving content from the CDN.The Federal Circuit reversed the dismissal of Cooperative’s infringement suit. The complaint contains several alleged inventive concepts which the specification touts as specific improvements in the distribution of data compared to the prior art, which should have precluded the district court’s holding on ineligibility (35 U.S.C. 101). One such concept is the required dynamic P2P network wherein multiple peer nodes consume the same content and are configured to communicate outside the CDNs. Another requires trace routes to be used in content segmentation. View "Cooperative Entertainment, Inc. v. Kollective Technology, Inc. (" on Justia Law

Provisur’s patent describes a method and system for “classifying slices or a portion cut from a food product according to an optical image of the slice.” Some food products, like bacon or cold cuts, are packaged and sold in groups of slices and “in accordance with a particular weight requirement.” Systems of conveyors and slicers create and gather these groups for packaging. The patent explains that, while slicing apparatuses and conveyor systems were known in the art, it remained “desirable to provide a system which would be directly responsive to the quality of cut slices and which would provide a compact and effective arrangement to classify slices based on fat content and fat deposits.” The patent describes an apparatus that includes a slicing station with a blade for removing slices from a food product.On inter partes review, the Patent Trial and Appeal Board concluded that Weber had proved unpatentable as obvious claims 1–10, 13, and 14 but not claims 11 or 12. The Federal Circuit vacated in part. The Board erred in deciding that claims 11 and 12 are not obvious; on remand, should the Board find the independent claims obvious after considering the surface-area limitations, claims 11 and 12 are also obvious in view of the Board’s determinations regarding claims 2, 6, and 7.

Johnson was a Dyess Air Force Base firefighter from 2017-2019. In 2018, Johnson’s mother came to live with Johnson's family. She took around 13 pills to treat health issues; Johnson was taking “seven or eight” pills. The Air Force subsequently selected Johnson for a mandatory random drug test. He tested positive for oxycodone and oxymorphone. Johnson told his supervisor, Ranard, that he had accidentally taken his mother’s pills instead of his own prescribed medication. Ranard proposed that Johnson be fired. The deciding officer, Lieutenant Colonel Fletcher, fired Johnson, explaining that he could not “risk the possibility of Johnson] coming to work again under the influence of illicit drugs.” At an arbitration hearing, Fletcher testified that he “just [didn’t] believe” that Johnson accidentally took his mother’s pill, having consulted his wife, a registered nurse, and his brother-in-law, a nurse practitioner, who “confirmed that the likelihood of that happening is slim to none.” The arbitrator denied Johnson’s grievance, affirming his termination.The Federal Circuit reversed and remanded. Fletcher’s ex parte communications violated Johnson’s right to due process. When Fletcher’s relatives allegedly “confirmed” that the chances of Johnson taking his mother’s pill were “slim to none,” they were not confirming information in the record; they were providing new opinions on the evidence.

In the tenth administrative review of the antidumping order on steel nails from China, the U.S. Department of Commerce found that Pioneer did not cooperate to the best of its ability with Commerce’s request for information, Commerce applied adverse facts available (AFA) and assigned an antidumping margin of 118.04 percent to Pioneer. Following the 2013 third administrative review, Commerce had announced that “all other future respondents for this case report all FOPs [factors of production] data on a CONNUM-specific [control number] basis using all product characteristics in subsequent reviews, as documentation and data collection requirements should now be fully understood by [the particular respondent] and all other respondents.” CONNUM is Commerce jargon for a unique product.The Trade Court and the Federal Circuit affirmed. Commerce’s 2013 pronouncement reflects a statement of policy, not the agency’s explicit invocation of general legislative authority; the CONNUM-specific rule is not subject to notice-and-comment rulemaking under the APA. The use of the CONNUM rule is not inconsistent with 19 U.S.C. 1677b, concerning the calculation of the normal value of merchandise. Commerce determined that CONNUM-specific data is essential for the accurate calculation of costs due to the variations in the physical characteristics of the merchandise. Pioneer did not provide required answers, so the application of AFA was supported by substantial evidence. View "Xi’an Metals & Minerals Import & Export Co. Ltd. v. United States" on Justia Law

The Department of Veterans Affairs rating schedule standardizes the evaluation of how severely diseases and injuries resulting from military service impair veterans’ earning capacity, 38 C.F.R. 4.1. The rating schedule is divided into diagnostic codes that provide disability ratings for various symptoms or conditions. The Federal Circuit, pursuant to 38 U.S.C. 502, reviewed the VA’s interpretation of two diagnostic codes: DCs 5055 and 5257: the “Knee Replacement Manual Provision” and the “Knee Joint Stability Manual Provision.” The court concluded that DC 5055 is ambiguous as to whether it includes partial knee replacements and, that under controlling Supreme Court precedent, the Secretary’s interpretation is not entitled to deference. A “Guidance” promulgated to clarify that the Provision applied only to total joint replacement did not go through the notice-and-comment procedure followed when the original Diagnostic Code was enacted. The court, therefore, applied the “pro-veteran” canon of construction. The court dismissed the challenge to the Knee Joint Stability Manual Provision as moot because the Secretary rescinded the Manual provision. View "Nova v. Secretary of Veterans Affairs" on Justia Law

Polaris’s 993 patent, titled “Control Component for Controlling a Semiconductor Memory Component in a Semiconductor Memory Module,” explains that the control component can send both address signals and control signals through the same leads, allowing the control component to perform its functions with fewer leads. Its 505 patent involves a shared-resource system in which logical controls are used to manage resource requests.In inter partes review (IPR) proceedings, the Patent Trial and Appeal Board determined that all challenged claims are unpatentable. The Federal Circuit affirmed. Because the Board decided the merits before Polaris filed its motion to terminate the IPR Polaris’s motion was untimely. The Board properly exercised its discretion. The court rejected Polaris’s argument that the Board misconstrued the claim terms “memory chips” and “semiconductor memory component” within the claim phrase “wherein the semiconductor memory component comprises a plurality of memory chips.” Prior art discloses all claim limitations under the Board’s claim constructions. The Board correctly adopted Polaris’s expert’s definition of “single buffer” as the broadest reasonable interpretation consistent with the specification, which discloses that resource tags "may be located in disparate locations." Substantial evidence supports a finding that the prior art discloses a “resource tag buffer.” View "Polaris Innovations Ltd. v. Brent" on Justia Law

Sawstop requested patent term adjustments (PTA) under 35 U.S.C. 154(b)(C), which grants day-for-day extensions for delays attributable to appellate review by the Patent Trial and Appeal Board or by a Federal court in a case in which the patent was issued under a decision in the review reversing an adverse determination of patentability.With respect to the application that led to the issuance of the 476 patent, the Board had affirmed the rejection of claim 11 on new grounds. On remand, SawStop filed amendments and a request for continued examination. The examiner eventually allowed claim 11. The PTO made no adjustment to the patent's term because “the patent only issue[d] after further prosecution” and amendment. The district court and Federal Circuit agreed. Because claim 11 was subject to a new ground of rejection on appeal, the application was not “issued under a decision in the review reversing an adverse determination of patentability.” With respect to the 796 patent, PTA had been granted for the delay incurred in the successful reversal of the rejection of claim 2 but was not granted for Sawstop’s appeal to the district court because the appeal did not “revers[e] an adverse determination of patentability.” Claim 1 remained subject to an outstanding provisional double patenting rejection and was unpatentable both before and after the appeal. Claim 1 was canceled and did not issue in the patent. View "SawStop Holding LLC v. Vida;" on Justia Law
