Justia Patents Opinion Summaries

Plaintiff owns the 245 Patent, which originally issued in 2005 and claims p-GlcNAc, a polymer extracted from another polymer called chitin, that accelerates hemostasis (the process which causes bleeding to stop) and is useful in trauma units for treating serious wounds. The district court found infringement. While the case was pending, the patent was re-examined; the scope of the claims changed. The Federal Circuit vacated an injunction and award of damages and remanded. Defendant has absolute intervening rights with respect to products manufactured before the date of reissue. The court must determine whether defendant has equitable intervening rights with respect to products manufactured after the date of reissue. A contention that the patent, as originally issued, was invalid is moot. View "Marine Polymer Tech., Inc. v. Hemcon, Inc." on Justia Law

The Patent, entitled "Spread Spectrum Digital Screening," issued in 1997 and relates to digital half-toning, a process of converting a continuous tone image, such as a photo, to a half-tone image, consisting of a pattern of minute dots. Newspapers are half-tone. In an infringement case, the district court granted a motion to stay the case against the Kodak Customers pending the outcome of plaintiff's action against Kodak in New York. The Federal Circuit dismissed for lack of jurisdiction, finding that there was no final judgment within the meaning of 28 U.S.C. 1295(a)(1), and and that the the decision did not otherwise qualify as an appealable order.View "Spread Spectrum, LLC v.

The jury found that Amazon's 1-click purchasing system infringes plaintiff's 710 patent, entitled "Object-Based On-Line Transaction Infrastructure," which covers an online purchasing system, but that all of the claims of the patent were invalid, and that Amazon did not infringe any of the other patents at issue. The judge granted a plaintiff's post-verdict motion and ruled that the 710 patent claims were not invalid. The Federal Circuit reversed the post-verdict ruling and held that each asserted claim of the 710 Patent is invalid as anticipated and the asserted claims of the other patents remain valid and not infringed.View "Cordance Corp. v.

The 605 and 247 patents cover aspects of genetically modified soybeans. The patent-holder sued one of its licensed seed producers, alleging infringement rather than breach of the agreement between the two. The district found infringement and awarded about $84,000. The Federal Circuit affirmed, rejecting an argument that patent rights were exhausted with respect to all of the soybean seeds that are present in grain elevators as undifferentiated commodity. The court also rejected an argument that plaintiff could not recover pre-complaint damages because it did not provide actual notice and did not mark or require growers to mark second-generation seeds in compliance with 35 U.S.C. 287(a). Defendant had actual notice. View "Monsanto Co. v. Bowman" on Justia Law

The patent application discloses an improved diaper; traditional diapers are constructed using an absorbent core of fluff pulp, interposed between a water barrier sheet and a permeable layer. For highest absorption, fluff pulp is treated with a chemical cross-linking agent. The application described a diaper that would avoid the expense of using chemically cross-linked fluff pulp while retaining superior absorbency properties, by extracting wood pulp with a caustic substance at low temperature, followed by dry and fluff. The examiner rejected the application (35 U.S.C. 103) as obvious from a prior patent. The Board sustained the rejection. The Federal Circuit vacated and remanded because the basis of the Board's rejection differed from the basis given by the examiner. View "In re Leithem" on Justia Law

The 545 patent claims a method for distributing copyrighted products (songs, movies, books) over the Internet where the consumer receives a copyrighted product for free in exchange for viewing an advertisement, and the advertiser pays for the copyrighted content. The district court dismissed an infringement claim. The Federal Circuit reversed and remanded. The patent claims a "process" within the meaning of 35 U.S.C. 101. View "Ultramercial, LLC .

The patent, entitled "Tape Drive and Printing Apparatus," describes and claims a device for transfer printing. In transfer printing, ink is carried by a ribbon that is moved into contact with the substrate to be printed, and a print head impresses upon the ribbon and causes the ink to transfer from the ribbon to the substrate. In thermal transfer printing, the print head is heated, facilitating transfer and adherence of the ink to the substrate. Plaintiff sought a declaration that it was not infringing the patent. Following a claim construction hearing, the district court construed "driveable" and "drive" to mean " rotateable" and "rotate," as proposed by plaintiff, rejecting a broader construction proposed by defendant (patent holder). The Federal Circuit vacated and remanded for claim construction consistent with its view that "drive" is properly construed to mean the application of torque to the spools, whether the torque causes rotation or resists it.

Plaintiff's 398 patent application descends through a chain of continuations and division from the 566 application, which was filed on the same day as the 579 application and identified 579 as a co-depending application. The USPTO declared Patent Interferences against defendants. Defendants claimed that plaintiff's claims were unpatentable for lack of written description support, arguing that the phrase "the same day as the present application" meant the same day that the 398 application was filed, not the original 566 application's filing date. The Board agreed, and, because plaintiff relied on this material, held that the claims lacked written description support. The Federal Circuit subsequently decided a case, holding that the same incorporation language was sufficient. The parties continued to dispute how much of the 579 application was incorporated. The Federal Circuit affirmed one decision and vacated the other. The Board erred in its analysis regarding the incorporation by reference of the 579 application and in its claim construction in one interference. View "Harari v. Lee" on Justia Law

Plaintiff sought a declaratory judgment of invalidity and noninfringement with respect to defendant's patents, involving composite wear products used for crushing and grinding abrasive materials in industrial settings. The district court held that its claims were invalid under 35 U.S.C. 251 for impermissibly recapturing subject matter surrendered during reissue examination. The Federal Circuit reversed. The district court erred in construing the claim term "solid solution," and, therefore, in determining that the reissued claims impermissibly recaptured surrendered subject matter.

The district court granted summary judgment that all of the claims in plaintiff's patents were ineligible under 35 U.S.C. 101, which excludes from patentability "laws of nature, natural phenomena, and abstract ideas" because they were directed to the "abstract idea" that there is a relation between the infant immunization schedule for infectious diseases and the later occurrence of chronic immune-mediated (non-infectious) disorders. The Supreme Court vacated the Sixth Circuit's 2008 decision. On remand the Federal Circuit affirmed with respect to one patent's ineligibility, but vacated a portion of the judgment granted under the "safe harbor" provision of 35 U.S.C. 271(e)(1). One set of claims did not include putting knowledge to practical use, but was directed to the abstract principle that variation in immunization schedules may have consequences for certain diseases. Others require the further act of immunization in accordance with a lower-risk schedule, moving from abstract scientific principle to specific application. View "Classen Immunotherapies, Inc. v.
