Justia Intellectual Property Opinion Summaries

The challenged patents relate to certain improvements to electronic communications systems that lower the peak-to-average power ratio (PAR) of the transmitted signals. Lowering the PAR of a communications system is desirable because it reduces power consumption and the likelihood of transmission errors. The challenged patents specifically address a PAR problem that arises in the transmission of digital data using multicarrier communications systems, such as digital subscriber line (DSL) systems. In inter partes review proceedings, the Patent Trial and Appeal Board invalidated all claims of the two related patents as obvious in view of prior art, 35 U.S.C. 103. The Federal Circuit reversed. The fact findings underlying the Board’s obviousness determinations are not supported by substantial evidence. The Board based its findings on the assertions in Cisco’s petition, which the Board expressly adopted as its own findings and conclusions. No reasonable factfinder could find, based on Cisco’s petition and supporting expert declaration, that a person of ordinary skill would have recognized prior art’s disclosure of phase scrambling as a solution to reduce the PAR of other prior art.

Pharma Tech sued LifeScan for infringement of two patents that concern blood glucose monitoring systems for home use by individuals with diabetes. The shared specification of Pharma Tech’s patents states that the claimed inventions improve on prior art blood glucose monitoring systems by “eliminat[ing] several of the critical operator depend[e]nt variables that adversely affect the accuracy and reliability” of these systems. The specification explains that the invention accomplishes this objective by performing multiple Cottrell current measurements and comparing the results. “In a system that is operating correctly, the results should agree within reasonable limits.” The Federal Circuit affirmed summary judgment of noninfringement. Pharma Tech agreed that the accused products do not literally infringe the claim. Prosecution history estoppel bars the claims for infringement under the doctrine of equivalents; the accused system falls within the claim scope surrendered by the inventors during prosecution of the patent.

IPR’s 244 patent recognizes two types of wireless networks: a wireless local area network, which allows a user to wirelessly connect a portable electronic device to an access point, e.g., a router, that is in turn connected to a network and a cellular network, in which geographic regions are divided into “cells” that each contain a “base station.” The 244 patent claims a “subscriber unit,” e.g., a mobile device, that can automatically select the best available wireless network and then connect to it. The Patent Trial and Appeal Board found multiple claims obvious based on prior art references. The Federal Circuit remanded as to claim 8, finding insufficient record support for the determination that claim 8 is invalid as obvious. The court concluded that the evidence to which the Board pointed failed—either individually or collectively— to support the conclusion that there would have been a motivation to combine the relevant prior art references. On remand, the Board again found claim 8 unpatentable. The Federal Circuit again remanded. The only additional evidence the Board cited in support of its conclusion on remand was not part of the record before the Board and the decision remains unsupported.

GAT’s 243 patent discloses a “method and system for providing an online game, in which ability information of a unit associated with a pilot is enabled to change as ability information of the pilot changes.” In July 2015, GAT filed a complaint accusing Wargaming and its affiliate, Wargaming.net, of infringing the patent. GAT's process server served Wargaming.net’s registered United Kingdom agent in December 2015; the summons was not signed by the clerk of court and did not bear the court’s seal. GAT’s attorney also mailed a copy of the complaint and summons to Wargaming's Cyprus office. In February 2016, Wargaming indicated that it did not believe that service was properly effected on either Wargaming entity but that Wargaming would waive service in exchange for an agreement to have until April to respond to the complaint. No formal waiver was filed. In March 2016, Wargaming appeared at a scheduling conference. In April 2016, Wargaming moved to dismiss. On March 13, 2017, Wargaming filed its petition for inter partes review (IPR), asserting that it was not barred by 35 U.S.C. 315(b)'s one-year limitation from requesting IPR because it had not been served. The Patent Board concluded that neither the UK service nor the Cyprus service triggered the time bar and that several claims would have been obvious over prior art. The Federal Circuit affirmed. GAT did not preserve its specific arguments for why service was proper or that Wargaming’s counsel waived service. The court upheld the Board’s construction of the terms “unit,” “pilot,” and “ability” in making its findings of obviousness. View "Game & Technology Co., Ltd. v. Wargaming Group Ltd." on Justia Law

KPN sued Gemalto for infringement of its 662 patent, which concerns “systemic error” in the physical transmission of information over the air, The district court found four claims patent-ineligible under 35 U.S.C. 101, as reciting no more than mere abstract data manipulation operations, such as “reordering data and generating additional data.” The Federal Circuit reversed. These claims are directed to an improved check data generating device that enables a data transmission error detection system to detect a specific type of error that prior art systems could not. The 662 patent solves prior art problems by varying the way check data is generated by varying the permutation applied to different data blocks. Varying the permutation for each data block reduces the chances that the same systematic error will produce the same defective check data across different data blocks. Claims 2–4 thus replace the prior art check data generator with an improved, dynamic check data generator that enables increased detection of systematic errors that recur across a series of transmitted data blocks. The appealed claims represent a nonabstract improvement in the functionality of an existing technological process and not simply an abstract idea of manipulating data. View "Koninklijke KPN N.V. v. Gemalto M2M GMBH" on Justia Law

Columbia’s 270 patent is a utility patent directed to materials that use a pattern of heat-directing elements coupled to a base fabric to manage heat through reflection or conductivity. Figures in the patent depict the material’s use in cold weather and camping gear. Its 093 patent is a design patent drawn to the “ornamental design of a heat reflective material.” In an infringement suit against Seirus, the jury found two claims in the 270 patent invalid as anticipated and obvious. The court entered summary judgment fining the 093 patent infringed. The Federal Circuit affirmed that the claims were invalid but reversed the summary judgment of infringement. In evaluating the prior art, the court erroneously compared Columbia’s design, Seirus’s product’s design, and a prior art patent design side-by-side before concluding that “[t]he overall visual effect of the Columbia and Seirus designs are nearly identical and if the logo was removed from the Seirus design, an ordinary observer would have great difficulty distinguishing between" the designs.” In evaluating prior art and wave thickness, the district court made a finding of fact—whether an element of Seirus’s design would give an ordinary observer a different visual impression than Columbia’s design—over a disputed factual record. Such questions should be resolved by a jury. View "Columbia Sportswear North America, Inc. v. Seirus Innovative Accessories, Inc." on Justia Law

On inter partes reexamination after the Federal Circuit vacated the Patent Trial and Appeal Board’s prior decision, the Board reversed the patent examiner’s rejection of new claims presented by Firepass (the patent owner). The patent discloses a fire prevention and suppression system that prevents and extinguishes fires using breathable air instead of water, foam, or toxic chemicals— each of which can present risks to personnel or electronic equipment. The invention is based on the inventor’s alleged discovery that a low-oxygen (hypoxic” but normal pressure (normbaric) atmosphere inhibits fire ignition and combustion, yet remains breathable for humans. The Federal Circuit vacated the Board’s reversal of the examiner’s rejection of the claims. The Board erred in its analogous art analysis by declining to consider record evidence relied on by Airbus to demonstrate the knowledge and perspective of a person of ordinary skill in the art at the time of the invention. The court remanded for consideration whether a particular prior art reference is analogous art in view of the four prior art references relied on by Airbus to demonstrate the knowledge and perspective of a person of ordinary skill in the art at the time of the invention.

Ericsson’s 052 patent describes and claims a “direct conversion receiver” for wireless communication systems that may receive signals from systems that operate at different frequency bands. On inter partes review, the Patent Trial and Appeal Board found that all of the challenged claims are unpatentable on the ground of obviousness, 35 U.S.C. 103. The Federal Circuit affirmed, finding that substantial evidence established that a specific foreign publication is an available reference against the patent. The article at issue was published in a German periodical whose cover states the date “Mai/Juni” 1996, more than one year earlier than Ericsson’s filing date of July 1, 1997. While journal issue did not reach the UCLA library until October 1996, substantial evidence supports the ruling that it was accessible to the public in the May/June 1996 period. Substantial evidence also supports the finding that the article renders obvious the claim 18 “steps of generating a first oscillator signal and frequency dividing the first oscillator signal to generate the in-phase and quadrature oscillator signals prior to the step of mixing.” View "Telefonaktiebolaget LM Ericsson v. TCL Corp." on Justia Law

The 2012 patent application relates to the construction of travel trailers with two compartments, living quarters and a garage portion, separated by a wall assembly. Claim 1 covers a travel trailer with first and second compartments separated by a wall assembly which is movable so as to alter the relative dimensions of the compartments without altering the exterior appearance of the travel trailer. Claim 2 covers a travel trailer having compartments separated by a wall assembly having a side member located adjacent to and movable in parallel with respect to a sidewall of the trailer, and the wall assembly moved along the longitudinal length of the trailer by drive means positioned between the side member and the sidewall. The examiner rejected both claims under 35 U.S.C. 102(b) as anticipated by patents that describe a conventional truck trailer and that describe a bulkhead for shipping compartments. The inventors argued that a “travel trailer” is “a type of recreational vehicle” and that the examiner erred by rejecting the claims without addressing the level of ordinary skill in the art. The Board affirmed, concluding the preamble term “travel trailer” is a mere statement of intended use that does not limit the claim. The Federal Circuit reversed. The Board erred in concluding “travel trailer” does not limit the scope of the claims; "no one would confuse a travel trailer with a truck trailer." View "In re: Fought" on Justia Law

In “Arthrex,” the Federal Circuit concluded that the appointments of Administrative Patent Judges (APJs) violated the Appointments Clause and vacated a decision made by a panel of APJs. Customedia sought to assert the same challenge. The Federal Circuit denied a motion to vacate, finding that Customedia forfeited its Appointments Clause challenge. Arguments not raised in the opening brief are waived. Appointments Clause challenges are not jurisdictional and must be properly raised on appeal. Customedia did not raise any semblance of an Appointments Clause challenge in its opening brief or raise this challenge in a motion filed prior to its opening brief.
