Justia Intellectual Property Opinion Summaries

Rembrandt sued for infringement of two patents that share a specification and claim priority to a provisional application filed in 1997, describing “a system and method of communication in which multiple modulation methods are used to facilitate communication among a plurality of modems in a network, which have heretofore been incompatible.” The patents explain that in the prior art “a transmitter and receiver modem pair can successfully communicate only when the modems are compatible at the physical layer,” so that “communication between modems is generally unsuccessful unless a common modulation method is used.” The patents propose using the first section of a transmitted message (header) to indicate the modulation method being used for the substance of the message (payload). A jury found that Samsung infringed the patents, which were not invalid over prior art, and awarded Rembrandt $15.7 million in damages. The Federal Circuit affirmed the district court’s claim construction of “modulation method of a different type” as “different families of modulation techniques, such as the FSK family of modulation methods and the QAM family of modulation methods.” The court vacated and remanded an order denying Samsung’s motion to limit Rembrandt’s damages for alleged failure to mark patented articles.

Core’s 143 patent recites a mobile station, such as a mobile telephone, that is connected to a cellular system or network. It is directed to means for sending packet data from the mobile station to the network using a selected channel. In prior art, the mobile station would send the network information about the data packet so that the network could make the channel selection decision. Selection by the network wastes system resources, because it requires the mobile station to send a message to the network regarding the data packet the mobile station wants to transmit, and then requires the network to make the channel selection decision. The 143 patent describes the mobile station, not the network, making the uplink channel selection decision; the network provides the mobile station with parameters that the mobile station applies in determining whether to use a dedicated channel or a common channel, which reduces “the signaling load associated with the allocation of packet data transfer” and “the delay associated with the starting of data transfer.” The Federal Circuit affirmed a verdict that Apple did not infringe, based on a holding that the claim requires that the mobile station “must have the capability to perform ‘channel selection,’ even if that capability was not used during the actual alleged performance of the claimed method.” View "Core Wireless Licensing S.A.R.L. v.

Navartis’s 283 patent relates to a solid pharmaceutical composition suitable for oral administration, comprising a sphingosine-1 phosphate (S1P) receptor agonist and a sugar alcohol, which the patent explains is useful for the treatment of certain autoimmune diseases such as multiple sclerosis. According to the specification, S1P receptor agonists generally exhibit properties that make formulations suitable for oral administration of a solid composition difficult to create. However, “solid compositions comprising a sugar alcohol provide formulations which are particularly well suited to the oral administration of S1P receptor agonists." They also “provide a convenient means of systemic administration of S1P receptor agonists, do not suffer from the disadvantages of liquid formulations for injection or oral use, and have good physiocochemical and storage properties.” On inter partes review, the Patent Trial and Appeal Board found all original claims of the 283 patent and proposed substitute claims unpatentable as obvious. The Federal Circuit affirmed. The Board discussed independent grounds supporting the motivation to combine prior art, fingolimod and mannitol, in a solid oral composition. View "Novartis AG v.

Bivalirudin is a synthetic peptide used to prevent blood clotting in patients undergoing cardiac catheterization. Bivalirudin’s pharmacological properties were known before the filing of Medicines’ 727 and 343 patents and were covered by Medicines’ 404 patent, which expired in 2015. The claimed inventions of the 727 and 343 patents are directed to minimizing impurities in batches of bivalirudin, an active ingredient, typically distributed as a dry powder that must be compounded with a base before being administered to a patient as an intravenous injection. Medicines received FDA approval to market a base-compounded bivalirudin drug product in 2000, and has sold the approved product since 2001 under the tradename ANGIOMAX®, before the critical date of the 727-343 patents. Mylan submitted an Abbreviated New Drug Application, seeking to market a generic version of ANGIOMAX. The district court held that the 343 patent was not infringed because Mylan did not satisfy the “efficient mixing” limitation of asserted claims and that the 727 patent was infringed because its asserted claims did not include an “efficient mixing” limitation. Without addressing the validity of the patents, the Federal Circuit reversed as to the 727 patent and affirmed as to the 343 patent. Both include a “batches” limitation that requires batch consistency, which, according to the patents, is achieved through efficient mixing. Efficient mixing is required by the asserted claims of both patents. View "The Medicines Co. v. Mylan, Inc." on Justia Law

The Novartis Patents-in-Suit belong to the same patent family, entitled “TTS Containing an Antioxidant,” and disclose a “[p]harmaceutical composition comprising” a compound commonly known as rivastigmine “in free base or acid addition salt form and an antioxidant,” “useful . . . for the treatment of Alzheimer’s disease.” The U.S. Patent and Trademark Office’s Patent Trial and Appeal Board (PTAB) found that various claims would have been obvious over prior art, 35 U.S.C. 103(a). The Federal Circuit affirmed, rejecting an argument challenging the PTAB’s conclusion that prior judicial opinions did not control its inquiry and the PTAB’s factual findings in support of its obviousness conclusion. The court concluded that the record here was differed from that in the prior litigation cited by Novartis and that substantial evidence supported the PTAB’s findings with respect to motivation to combine prior references.

Wasica’s (now-expired) 524 patent describes systems for monitoring tire pressure in vehicles. The patent addresses problems with inaccuracy in prior art by synchronizing components of the tire pressure system. In two inter partes review proceedings, the U.S. Patent & Trademark Office’s Patent Trial and Appeal Board found certain claims unpatentable as anticipated or obvious. The Federal Circuit affirmed in part and reversed in part. View "Wasica Finance GMBH v. Continental Automotive Systems, Inc." on Justia Law

The 631 application, entitled “Glenoid Implant for Minimally Invasive Shoulder Replacement Surgery,” describes an invention related to “rotator cuff sparing procedures and associated devices for shoulder replacement surgery.” The application improves on the prior art by offering “simple and less invasive perpendicular access to the humeral and glenoid joint surfaces,” which “spares the rotator cuff tendons and allows for a quicker and more functional recovery.” The surgery described in the application involves two main steps. First, the surgeon removes “a minimal amount of bone from the peripheral surface of the glenoid”—a process called reaming. Second, the surgeon places an implant in the reamed cavity. The Patent Trial and Appeal Board concluded that several claims were anticipated by prior art, 35 U.S.C. 102(b). The Federal Circuit reversed; the finding of anticipation was not supported by substantial evidence. View "In re: Chudik" on Justia Law

The Tuschl patents relate to RNA interference, a process for “silencing” genes from expressing the proteins they encode, which may be useful in treating various diseases. In 2000, before the invention was reduced to practice, Dr. Tuschl published an article describing the discoveries. Weeks later, Dr. Bass published a mini-review that focused on Tuschl’s article and included her own hypotheses about enzymatic processes that may be responsible for the RNAi activity reported in Tuschl’s article. Tuschl read Bass’ article and recognized and successfully tested her hypothesis. Bass’ mini-review was cited as prior art during prosecution of the Tuschl patents, each of which issued. Bass sued for correction of ownership, claiming that Bass should be named as either a sole or joint inventor of the patents. During depositions, Bass made admissions undermining allegations that Bass reduced the Tuschl invention to practice and that Bass collaborated with the inventors. On the eve of the deadline for dispositive motions, Bass withdrew the sole inventorship claims, but not the joint inventorship claim. The district court rejected the joint inventorship claims on summary judgment, finding no evidence of collaboration between Bass and the Tuschl inventors. The district court declined a request for eight million dollars in attorney fees under 35 U.S.C. 285, The Federal Circuit affirmed, finding that the case was not objectively unreasonable when all reasonable inferences were drawn in Bass's favor.

TVIIM’s 168 patent, entitled “Method and Apparatus for Assessing the Security of a Computer,” describes “a security system which identifies security vulnerabilities and discrepancies for a computing system.” The patent both identifies potential security threats to a computer and, under certain conditions, recommends action to a user to stop the threat. TVIIM sued McAfee. A jury determined that McAfee did not infringe the 168 patent and that the 168 patent was invalid. The Federal Circuit affirmed, finding that substantial evidence supported the jury’s findings of non-infringement and invalidity under the court’s single construction of the claim terms: “as a result of/in response to,” “various utility functions,” and “reporting the discovered vulnerabilities.” TVIIM did not seek construction of any of the three terms at trial.

The patents-in-suit relate to soybeans genetically engineered to tolerate herbicide, and, particularly, to the Bayer-developed dmmg gene. The parties disagreed over the scope of Bayer’s license of the patents to MS Tech, specifically, whether the license granted MS Tech a broad license to commercialize and sublicense the soybean technology. MS Tech had sublicensed to Dow. When Bayer sued Dow for infringement, Dow raised that sublicense as an affirmative defense. The district court entered summary judgment in favor of Dow; the Federal Circuit affirmed. The district court then awarded Dow attorney fees under 35 U.S.C. 285, declaring this an "exceptional case.” The Federal Circuit affirmed, noting Bayer’s weak positions on the merits and litigation conduct. “Bayer’s own witnesses as well as key documents contradicted Bayer’s contorted reading of the contract.” Bayer’s arguments were “fallacious” because they were “implausible” and “made no business sense” in light of the facts surrounding the agreements and their negotiation.
