Justia Patents Opinion Summaries

The patent, entitled “Intermediate Network Authentication,” concerns internet security, and was developed by a scientist at the Naval Research Laboratory (NRL). The NRL allowed the patent to lapse for nonpayment of the 7.5-year maintenance fee. Two weeks after the lapse, NRL received an inquiry from Network Signatures about licensing the patent and successfully petitioned the Patent and Trademark Office (PTO) to accept delayed payment of the fee. Network Signatures sued State Farm for infringement of the patent. In defense, State Farm asserted that the patent was permanently unenforceable on the ground that the NRL patent attorney had engaged in inequitable conduct by “falsely representing” to the PTO that the NRL’s non-payment of the maintenance fee was “unintentional.” The district court granted summary judgment of inequitable conduct, and found the patent unenforceable. The Federal Circuit reversed, holding that the PTO Director acted in accordance with law and within his discretion in excusing the delayed payment, and that inequitable conduct was not established.

Conventional memory circuits asynchronously transfer all of the data upon request, which can tie up the computer system for long periods of time and create a “bottleneck” that slows down computer operations. The patent at issue solves the problem using a synchronous memory system to transfer data. The Board of Patent Appeals and Interferences held that certain claims of the patent were invalid for anticipation and obviousness. The Federal Circuit held that the Board correctly construed claims: that the “external clock signal” only requires the clock to be periodic during the data input phases, as opposed to being periodic for all system operations and that “write request” could include “the state of a signal,” which is usually represented by a single bit. The court vacated with respect to the obviousness determination. View "Rambus Inc. v. Rea" on Justia Law

BDI is the owner a design patent and the manufacturer of slippers known as SNOOZIES®. High Point manufactures and distributes the accused FUZZY BABBA® slippers, which are sold through various retailers, including Meijer, Sears, and WalMart. BDI sent High Point a cease and desist letter, asserting patent infringement. High Point sought a declaratory judgment. The district court held BDI’s asserted design patent invalid on summary judgment and dismissed BDI’s trade dress claims with prejudice. The Federal Circuit reversed. The district court applied the incorrect standard; a reasonable jury could, under the correct standard, find the patent not invalid based on functionality. On remand, the district court should weigh High Point’s notice of BDI’s trade dress claim and initial belief that its original complaint encompassed such a claim and the absence of apparent prejudice to High Point against the fact that BDI had always been in possession of the information added in the proposed amendments and could have asked to clarify its pleading sooner.

The patents at issue relate to methods and devices for sealing a vascular puncture, which occurs when a medical procedure requires a puncture through the skin and into a vein or artery to insert a medical device, such as a catheter, into a patient’s vasculature. After such a procedure, the medical professional typically removes the medical device from the vasculature. Prior to development of the technology at issue, the medical professional was then required to apply external pressure to the puncture site until clotting occurred, sometimes for an extended period of time. This caused discomfort and increased the recovery time. The Janzen and Fowler patents disclose methods and devices for sealing a vascular puncture to improve patient recovery. The district court held that the safe-harbor provision of 35 U.S.C. 121 protects the Janzen patent from invalidity due to double-patenting; construed key terms in the Janzen patent; and found that the Fowler patents were not invalid for obviousness. The Federal Circuit reversed the safe harbor ruling, which rendered the rulings regarding the claim constructions moot, and affirmed that the Fowler patents are nonobvious and not shown to be invalid.

In 1997 Wawrzynski was awarded the 990 patent, entitled “Method of Food Article Dipping and Wiping in a Condiment Container.” The description illustrates a condiment container that has a flexible cap with a slitted opening. A user introduces a food article, such as a French fry, into the container through the slit and dips it into the condiment. As the food article is removed, the flexible cap wipes away excess condiment , reducing the likelihood of a drip or spill. . Wawrzynski presented his “Little Dipper” concept, permitting a consumer to either dip or squeeze, to Heinz in a 2008. Heinz indicated that the company was not interested in the product, but months later, released its new “Dip & Squeeze®” packet. Wawrzynski filed a lawsuit asserting breach of an implied contract and unjust enrichment. Heinz counterclaimed that Heinz did not infringe the patent and that the patent was invalid. The district court entered summary judgment, holding that federal patent law preempted the state law claims and that Wawrzynski failed to prove infringement. The Federal Circuit transferred to the Third Circuit, stating that its subject matter jurisdiction over patent disputes derives solely from the complaint, not from any counterclaim.

Jang, a doctor and inventor, sued BSC, the company to which Jang assigned his coronary stent patents, for breach of the patent assignment agreement, which required BSC to share profits from the patents with Jang, including any damages it recovers from third-party infringers. In 2010, BSC settled a claim against Cordis for infringement in combination with anther claim that Cordis had against BSC. BSC made a payment to Cordis, and the parties exchanged several patent licenses. BSC then denied that it had recovered any damages that it was obligated to share with Jang. The Third Circuit reversed judgment on the pleadings in favor of BSC. Two of Jang’s claims are sufficient to survive judgment on the pleadings: that BSC breached the contract because the cash offset qualifies as a “recovery of damages” and that BSC violated the implied covenant of good faith and fair dealing by structuring a settlement to thwart the agreed purpose of the patent assignment.

Accenture alleged infringement of its patent, which describes a “computer program ... for handling insurance-related tasks” and discloses software components of the program, including a “data component that stores, retrieves and manipulates data” and a client component that “transmits and receives data to/from the data component.” The client component includes a business component that “serves as a data cache and includes logic for manipulating the data.” The program also describes a controller component to handle program events and an adapter component to interface with a data repository. The district court found all of the claims invalid under 35 U.S.C. 101. Accenture appealed only with respect to claims 1–7, directed to a system for generating tasks to be performed in an insurance organization, but did not appeal the similar method claims 8–22. The Federal Circuit affirmed, holding that the system claims at issue recite patent-ineligible subject matter both because Accenture was unable to point to any substantial limitations that separate them from the similar, patent-ineligible method claim and because the system claim does not, on its own, provide substantial limitations to the claim’s patent-ineligible abstract idea.

Bayer’s patent concerns genetically modifying plants to confer resistance to a common herbicide (2,4-D) by inserting a particular DNA segment into plant cells, which reproduce to create new cells that contain that gene. Those cells produce an enzyme that catalyzes a biochemical reaction with 2,4-D in which the herbicide is broken down into something harmless to the plant. A plant with the gene survives 2,4-D application while surrounding weeds do not. At the time of the patent application, the inventors had sequenced one gene coding for one enzyme, using a test supposedly capable of finding other, similar genes. In writing the application, they claimed a broad category based on the function of the particular enzyme, defining the category by using a term with established scientific meaning. Years before the patent issued, experiments showed that the term did not apply to the particular enzyme whose gene was sequenced, but Bayer did not change its claim language. When Bayer sued Dow for infringement, Bayer recognized that the term’s established scientific meaning, did not cover the accused product, which was, itself, different from the enzyme whose gene Bayer’s inventors had sequenced. Bayer argued for broad functional claim construction. The district court entered summary judgment of noninfringement, citing particularly the great breadth of the asserted functional construction. The Federal Circuit affirmed. View "Bayer CropScience AG v. Dow AgroSciences, LLC" on Justia Law

TT’s 411, 768, 374, and 055 parents relate to software used for electronic trading on a commodities exchange, were issued in 2010-2011, and claim priority to applications filed in 2000. In consolidated infringement proceedings, the district court found the patents invalid for failure to comply with the written description requirement of 35 U.S.C. 112 and that prosecution history estoppel barred TT from asserting the 055 patent against software products that include certain display functions. The holdings were premised on a 2010 Federal Circuit decision involving two related patents from TT’s portfolio. The Federal Circuit reversed, holding that the earlier decision does not control the issues presented in this litigation. View "Trading Techs. Int'l v. Open E Cry, LLC" on Justia Law

Aevoe’s patent is directed to a touch screen protector for electronic devices, consisting of plastic film and a spacer that can be attached and removed without trapping air bubbles or dust. The spacer, sized to fit a particular device and having an adhesive for attachment and removal, surrounds the thin plastic film and is thick enough that the film does not make direct contact with the screen, but thin enough that a user can make contact with the touch screen by pressing the film. Aevoe sued, alleging that AE’s touch screen products infringed the patent. Despite receiving notice of restraining and show cause orders, AE did not respond. The district court issued a preliminary injunction. AE moved to reconsider and vacate, arguing that the patent was invalid. The court amended the injunction to omit “trademark language.” AE did not appeal. Aevoe subsequently filed an amended complaint, claiming that S&F sold infringing products obtained from AE and requested that both AE and S&F be held in contempt. After examining a redesigned AE product, the court found that added channels were a nonfunctional and trivial attempt to design around the patent and held all defendants in contempt. The Federal Circuit dismissed an appeal as untimely; amendment of the injunction was a mere clarification and did not substantially change the legal relationship between the parties.
