Justia Patents Opinion Summaries

Augme sued Yahoo! alleging infringement of certain claims of two patents that disclose adding functionality, such as media or advertisements, to a web page. Yahoo! counterclaimed that Augme and World Talk Radio infringed certain claims of its patent. After claim construction, the court granted Yahoo! summary judgment of noninfringement and held that certain means-plus-function terms in claims 19 and 20 of Augme’s patent were indefinite. The parties stipulated to infringement of the asserted claims of Yahoo!’s patent based on the court’s claim construction. The Federal Circuit affirmed that Yahoo!’s accused systems do not infringe the Augme patents either literally or under the doctrine of equivalents and that certain claims are indefinite. The court also upheld the district court’s construction of the claim term “server hostname.”View "Augme Techs, Inc. v. Yahoo! Inc." on Justia Law

Suffolk owns a patent directed to methods and systems for controlling a server that supplies files to computers rendering web pages. The patent discloses using the address of the referring web page to determine whether to serve a file, and if so, which file. The district court entered summary judgment of invalidity, holding that claims 1, 7, and 9 were anticipated by a Usenet newsgroup post. Suffolk then stipulated that, in light of the district court’s prior art, claim construction, and expert testimony rulings, claim 6 was also anticipated. The Federal Circuit affirmed.

ESR’s 236 patent, as amended, claims a computer security device and method for preventing unauthorized individuals from obtaining access to a local computer network. Its specification describes an “intelligent network security device” (INSD), capable of balancing the desire for network security against the need for network accessibility. The INSD protects a local network by: monitoring the data packets flowing into and out of the network in order to detect suspicious patterns of communications; assigning weighted values to any threatening activity it detects; and blocking communications based on their assigned weight using a firewall. A third party requested reexamination of the original patent and the PTO considered prior art. The examiner rejected certain claims as obvious. The Patent Trial and Appeal Board and the Federal Circuit affirmed. View "In re: Enhanced Sec. Research LLC" on Justia Law

The central processing unit (CPU) enables a computing device to execute instructions contained in software. For software to run on CPU, it must be compiled or translated from high-level programming language, written in a human-readable syntax (source code), into machine-readable form (machine code), which is processor-specific. Particular compilers can only translate programs into machine code for particular processors. Java is programming language that allows developers to write programs that can run on different processors without being recompiled for each system by using a single compiler that translates Java programs into “bytecodes” instead of processor-specific machine code. Java bytecodes do not run directly on the CPU, but on a Java Virtual Machine (JVM) that translates them into processor-specific machine code. Programs written in Java can run on any platform and any operating system. Computing devices also vary in how they store data in memory. Machine code or “instruction sets” may be “stack-based” or “register-based.” Although most modern processors use a register-based approach, Java bytecodes are stack-based. A device using a register-based processor can run Java programs using a JVM that translates into register-based instructions, but it takes longer. Nazomi has two patents that address the issue, describing a hardware-based JVM capable of processing stack-based instructions, that also can run legacy (register-based) applications without using the JVM. Defendants are manufacturers that incorporate processors into their products. Nazomi sued, alleging patent infringement. The district court granted defendants summary judgment, construing the asserted claims to require a hardware and software combination capable of processing both register-based and stack-based instructions; without the enabling certain software, the hardware at issue cannot process stack-based instructions. Defendants’ apparatuses do not include that software. The Federal Circuit affirmed. View "Nazomi Commc'ns, Inc. v. Nokia Corp." on Justia Law

TecSec’s 702, 452, and 781 Patents derive from a common parent application and disclose a system and a method for providing security in a data network by nesting encrypted objects into other objects which are also encrypted, allowing a system to employ different security levels to restrict access to specific compartments of data. The district court found no infringement. The Federal Circuit reversed in part, holding that the court correctly construed the term “multi-level multimedia security,” but incorrectly limited the encrypted data to objects in multimedia form. The court also erred in holding that the term “digital logic means” was a means-plus-function limitation. TecSec may be able to prove infringement against every defendant except PayPal.

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.

Taurus sued DaimlerChrysler, alleging that external websites infringed its patent for “a computer system for managing product knowledge related to products offered for sale by a selling entity.” Daimler Chrysler asserted license and release defenses, asserted a breach of contract counterclaim, and filed a contract claim against third-party defendants (including Orion), which, it claimed violated a 2006 patent licensing agreement between DaimlerChrysler and Orion, to settle prior patent infringement suits. The district court entered summary judgment, finding that the accused websites did not infringe any asserted claims and that certain claims were invalid as anticipated by prior art. The district court found the DaimlerChrysler suit to be exceptional under 35 U.S.C. 285, and awarded damages of $1,644,906.12, for costs incurred in Chrysler’s defense. With respect to remaining issues, the district court: found that certain third parties were alter egos and declined to dismiss for lack of jurisdiction; held that the 2006 agreement did not provide a release to the infringement alleged in the patent suit; held that issues of fact remained as to whether certain third parties had breached a warranty in the 2006 agreement; held that Orion had breached the warranty; and imposed sanctions on Orion and another for pre-trial witness tampering (those parties were not permitted to present evidence to support their defense that Chrysler did not rely on the warranty). The Federal Circuit affirmed, except with respect to attorney fees. View "Taurus IP, LLC v. DaimlerChrysler Corp." on Justia Law

In a wireless system, devices communicate with fixed “base stations” according to “protocols,” which are standardized procedures that govern how data exchanged between devices is formatted, ordered, maintained, and transmitted. Effective wireless communication requires that the transmitting device and the receiving device follow the same protocol. Commil’s 395 patent covers a method of providing faster and more reliable handoffs of mobile devices from one base station to another as a mobile device moves throughout a network area. Cisco is a major supplier of WiFi access points and controllers. A jury found that Cisco directly and indirectly infringed specified claims of the 395 patent; that the specified claims were not invalid as indefinite, for lack of enablement, or as lacking adequate written description; and that Cisco was liable for $63,791,153 in damages and pre-judgment interest and costs. The Federal Circuit reversed in part, holding that the district court gave the jury a legally erroneous instruction concerning indirect infringement and that Cisco’s evidence of a good-faith belief of invalidity may negate the requisite intent for induced infringement. The district court did not err in granting a partial new trial. View "Commil USA, LLC v. Cisco Sys., Inc." on Justia Law

Versata’s patents relate to computer-based pricing of products. In prior art, each factor required separate database queries, so that determining a price was highly inefficient. The claimed invention identifies all the groups to which a customer belongs and all corresponding price adjustments and product-related factor. Versata marketed a successful product, Pricer, sold as a package with other Versata software or as an addition to enterprise systems offered by companies like SAP. While Versata’s patent application was pending, SAP released a new version of its software that contained hierarchical pricing capability, which, it stated, was like Pricer. Pricer sales faltered. Versata sued for infringement. In the first trial, the jury found that SAP directly infringed asserted claims, induced and contributed to infringement of one claim, and that the claims were not invalid, and awarded $138,641,000. The court granted JMOL of noninfringement of the 400 patent, but denied JMOL of noninfringement of the 350 patent. Before the second trial, SAP modified its products with a patch that prevented users from saving data into certain fields. The jury concluded that the products still infringed and awarded $260 million in lost profits and royalties of $85 million. The court entered a permanent injunction. The Federal Circuit vacated the injunction as overbroad, but otherwise affirmed. View "Versata Software, Inc. v. SAP Am., Inc." on Justia Law

Morsa’s patent application, entitled “Method and Apparatus for the Furnishing of Benefits Information and Benefits,” discloses both a method and an apparatus for receiving a benefit-information request from a user, searching a benefit information database for benefits matching the request, and then returning benefit information to the user. In the specification, Morsa defines benefits as any “‘things’ of value” given away to target entities. The Board of Patent Appeals and Interferences affirmed rejection of multiple claims. The Federal Circuit affirmed in part, finding that many claims would have been obvious in light of prior art. Vacating in part, the court held that the Board performed an incorrect enablement analysis in determining that certain claims were anticipated. View "In re: Morsa" on Justia Law
