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

Plaintiff holds a patent on formulations of a hypnotic sleep-inducing drug that is one of a class of compounds known as benzodiazepines. Pharmacological formulations of the drug have been marketed internationally for the treatment of insomnia since the 1970s, and in the United States since 1981. Plaintiff responded to an FDA filing by a competitor by filing an infringement claim. The district court found plaintiff's patents invalid on grounds of obviousness. The Federal Circuit affirmed. The only limitation of the disputed claims that was not fully disclosed by the prior art capsules is the lower dosage; those skilled in the art (physicians) have an undisputed preference for prescribing the lowest effective dose.

The district court entered summary judgment, finding that asserted patents relating to modernizing conventional elevator systems by allowing passenger to input their destinations when calling for an elevator were invalid for failure to meet the definiteness requirement of 35 U.S.C. 112. The Federal Circuit reversed and remanded. The district court erred in holding that the claimed "modernizing device" and "computing unit" limitations were means-plus-function limitations subject to the requirement and that the written descriptions failed to disclose any corresponding structure. The inventor did not draft the claims in "means for" format, and his decision to avoid the term "means" raises a strong presumption that the claimed "computing unit" connotes sufficiently definite structure to those skilled in the art.

The district court found infringement on a patent for coronary stents--stainless steel tubes that are surgically inserted into an occluded artery and expanded in place, opening the artery to blood flow. The court awarded damages calculated as a royalty on defendant's sale of the infringing product, but did not award enhanced damages or attorney fees, despite a jury finding of willful infringement. The Federal Circuit affirmed the determination of infringement, finding that the evidence supported a finding that the patent was not "obvious," and affirmed.the jury’s choice of a five-percent royalty as reasonable in light of trade practices and the economic and competitive circumstances. The court vacated the district court's denial of attorney fees and enhanced damages and remanded for a determination concerning the egregiousness of defendant’s conduct based on all the facts and circumstances, the test for enhanced damages.

The district court held that the patents-in-suit, relating to drug-eluting coronary stents used in the treatment of coronary artery disease, are invalid for failure to comply with 35 U.S.C. 112 for lack of adequate written description. The Federal Circuit affirmed. Determining whether a specification contains adequate written description requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art. No reasonable jury could have determined that the description was adequate.

Patent application 747, covering a mixing device for use in preparation of sugar-water nectar for certain bird and butterfly feeders, was rejected on grounds of obviousness. The examiner cited prior art on devices for mixing sugar-to-water ratios. The Board of Patent Appeals and Interferences affirmed. The Federal Circuit reversed, reasoning that the application described a device with moveable dividers to allow mixing of different ratios for different species, which is not analogous to the devices cited by the examiner.

The district court held that check-security products sold by defendant did not infringe plaintiffâs patent on a method and system for guarding against check fraud and forgery. The Federal Circuit reversed a holding that there could be no direct infringement because defendant did not direct or control the encrypting or printing steps referenced in the patent claims; the defendant could "use" the described process without controlling those steps. The court vacated summary judgment on a claim that defendant induced infringement by banks and disagreed with the district court's construction of a phrase in the claim. The specifications supported plaintiff's construction. The court acted within its discretion in denying a motion to amend the complaint to include a false advertising claim.

Companies sought a declaratory judgment of non-infringement of patents on diabetes testing products; the patent-holder claimed infringement. The district court found no infringement of two patents, found that several claims in one patent were anticipated, and found another patent (551) unenforceable due to obviousness and inequitable conduct. The Federal Circuit affirmed. With respect to patent 551, there was ample evidence to support a finding of intent to deceive the Patent Office in failing to disclose highly material statements made during revocation proceeding on a European patent. There was also ample evidence to support findings of non-infringement and of anticipation.

The holder of patents on an FDA-approved product that promotes eyelash growth claimed patent infringement and violation of California Business & Professions Code 17200 unfair competition provisions against companies marketing similar products. The district court dismissed the state law claims for lack of standing under an amendment to that law, enacted by the voters as Proposition 64. The Federal Circuit reversed and remanded. The complaint adequately alleged economic injury caused by defendants' unfair business practices; it is not necessary that the plaintiff had direct business dealings with the defendants.

The company filed a claim under the Tariff Act of 1930, 19 U.S.C. 1337, asserting infringement of its patents on microchip encapsulation innovations. The ITC found no violation. The Federal Circuit affirmed. Substantial evidence supported the finding of no infringement of one patent by 17 of 18 defendants. The court also affirmed the ITC's determination that the patent was not anticipated and its finding of patent exhaustion with respect to the eighteenth defendant. The claims with respect to other patents, which have expired, are moot.

Plaintiff develops and manufactures cable telephony and data products for cable system operators for use in Voice over Internet Protocol systems and sought a declaratory judgment that its customer did not infringe defendant's patents by using equipment purchased from plaintiff. The district court dismissed for lack of subject matter jurisdiction. The Federal Circuit reversed and remanded. Although economic injury alone is insufficient to create standing, the defendant's accusation of infringement against plaintiff's customer included an implicit assertion that plaintiff indirectly infringed or contributed to infringement of the patent. The defendant has not provided plaintiff with a covenant not to sue.
