Court Denies Motion to Amend Invalidity Contentions, Citing Defendant’s Failure to Show When It Could Have Discovered New Information

In MicroVention, Inc. v. Balt USA, LLC, the United States District Court for the Central District of California recently denied a defendant’s motion to amend its invalidity contentions to add additional written description and enablement arguments, finding a lack of diligence by the defendant. The court, which in patent cases “follows a schedule similar to that imposed by the Northern District of California,” emphasized the diligence that must be shown to warrant a party amending its invalidity contentions. Specifically, the court noted that “‘[t]he critical issue is not when [the party] discovered [the] information, but rather whether [it] could have discovered it earlier had it acted with the requisite diligence.’” (quoting Google, Inc. v. Netlist Inc., 2020 WL 1838693, at *2 (N.D. Cal. May 5, 2010)). As we recently reported, the District of New Jersey “adopted verbatim [its] Local Patent Rules from the Northern District of California.” TFH Publ’n, Inc. v. Doskocil Mfg. Co., 705 F. Supp. 2d 361, 365 (D.N.J. 2010). The court found that one of the defendant’s proposed amendments was based on the claim construction position the plaintiff had taken during the claim construction phase of the case. However, the court recognized that the plaintiff’s claim construction had not changed since the beginning of the case and, on that basis, found that...

Expert Report Cannot Be Used for Previously Undisclosed Invalidity Theories

The United States District Court for the Central District of California recently granted a plaintiff’s motion to strike portions of the defendant’s expert report for the untimely disclosure of new invalidity theories that were not previously disclosed in the defendant’s invalidity contentions. In Nichia Corporation v. Feit Electric Company, Inc., the plaintiff sought to strike from the defendant’s expert report: (1) an entirely new reference; (2) two new obviousness theories based on combinations of references not included in the defendant’s final invalidity contentions; and (3) a new written description argument. In ruling, the court highlighted the district’s Standing Patent Rules’ emphasis on “early notice” of infringement and validity contentions, that amendments to contentions require diligence by the moving party and that new infringement and invalidity theories cannot be introduced through expert reports. The Standing Patent Rules that the parties were following were initially set forth by Judge Guilford of the Central District of California. It has been noted that “Judge Guilford’s Standing Patent Rules are similar to the Local Patent Rules adopted by the Northern District of California.” Mort. Grader, Inc. v. First Choice Loan Servs. Inc., 811 F.3d 1314, 1321(Fed. Cir. 2016). And, relatedly, the District of New Jersey “adopted verbatim [its] Local Patent Rules from the Northern District of California.” TFH Publ’n, Inc....

Northern District of California Relies on the Safe Harbor Defense of Section 271(e)(1) to Resolve Infringement Cases Early

Two recent decisions from the Northern District of California show courts’ willingness to dispose of cases early in litigation through the safe harbor defense. The safe harbor of Section 271(e)(1) allows competitors, before the expiration of a patent, to engage in otherwise infringing activities if the use is “reasonably related to” obtaining regulatory approval. These two decisions provide pre-litigation and litigation guidance for life science companies that manufacture regulated products such as drugs and medical devices. The Supreme Court has construed the safe harbor to apply to drugs as well as medical devices and other products subject to Food and Drug Administration (FDA) approval. Section 271(e)(1) of the Patent Act provides that: “It shall not be an act of infringement to make, use, offer to sell, or sell within the United States or import into the United States a patented invention … solely for uses reasonably related to the development and submission of information under a Federal law which regulates the manufacture, use, or sale of drugs or veterinary biological products.” In Carl Zeiss Meditec v. Topcon Medical Systems, the N.D. Cal. granted with prejudice a motion to dismiss the plaintiff’s patent infringement claim based on product testing as barred by the safe harbor of § 271(e)(1). Carl Zeiss alleged that software testing by Topcon...

28 Days to Amend Contentions Following Disclosure of Preliminary Claim Constructions

In an interesting decision applying California’s Local Patent Rules, Northern District of California District Court Judge William Alsup held that “after receiving the other side’s preliminary claim construction disclosure under Rule 4-2, a party in a patent litigation must move promptly to disclose any back-up contentions it may wish (or eventually wish) to make for its infringement or invalidity case, in the event the other side’s claim construction is thereafter adopted or else any such back-up contentions will be deemed waived. Promptly means within 28 days at the latest.” Fluidigm Corp., et al. v. IONpath, Inc. at 4. Judge Alsup’s decision was his answer to “the question of the extent to which our patent local rules require infringement and invalidity contentions to set forth not only a party’s primary theory but also its backup theory in case its opponent’s claim construction prevails.” Id. at 1. In answering that question, Judge Alsup provided a brief exposition on California’s Local Patent Rules. “Before our local patent rules, parties struggled to determine the opposing party’s theory of liability via discovery requests, such as contentions interrogatories.” Id. at 6. The adoption of local patent rules “replaced the bone-crushing burden of scrutinizing and investigating discovery responses with the parties’ infringement and invalidity contentions.” In alleviating that burden, local patent rules...

Paragraph IV to Paragraph III Conversion Does Not Deprive a District Court of Subject Matter Jurisdiction in Hatch-Waxman Cases

In a significant Hatch-Waxman decision, a Delaware District Court recently denied the defendants’ motion to dismiss under Federal Rule of Civil Procedure 12(b)(1), rejecting the argument that the conversion of the defendants’ Paragraph IV certifications to Paragraph III certifications deprived the court of subject matter jurisdiction, but granted the defendants’ motion for partial judgment on the pleadings under Federal Rule of Civil Procedure 12(c). In H. Lundbeck A/S v. Apotex Inc., the defendants converted their Paragraph IV certifications for certain patents at issue to Paragraph III certifications. Under 21 U.S.C. § 355(j)(2)(A)(viii), an ANDA filer must make any one of four (I-IV) certifications for each Orange Book listed patent. A Paragraph IV certification is an ANDA filer’s statement that it intends to market its bioequivalent pharmaceutical product before the expiration of a patent listed as covering that product because the ANDA filer believes such patent is either not infringed or invalid. A Paragraph III certification is an ANDA filer’s statement that it will not market its bioequivalent product until after the expiration of a patent listed as covering that product. The Court reasoned that in a Hatch-Waxman action, subject matter jurisdiction exists when a patent owner alleges that the filing of an ANDA infringes its patent under 35 U.S.C. § 271(e)(2) and conversion from a...

“Good Cause” Not Required for Contention Amendments in the District of Delaware

In Bio Delivery Sciences International Incorporated v. Alvogen PB Research & Development LLC, a Delaware District Court recently denied the plaintiffs’ motion to strike two prior art references from the defendants’ supplemental invalidity contentions, reasoning that the defendants were not obligated, as the plaintiffs argued, to demonstrate good cause for the amendment. The court noted that the case’s scheduling order did not contain a “good cause” requirement for amending contentions or a requirement that contentions be amended before the date on which the defendants served their amended contentions. The court reasoned that, while the amended contentions did need to comport with the requirements of Fed. R. Civ. P. 26, an analysis under the Pennypack factors did not require striking the references. In particular, the “possibility of curing the prejudice” and “likelihood of disruption of trial” factors militated strongly in the defendants’ favor because the plaintiffs did not need further discovery on the references and could address them easily in their expert reports, which would not have any impact on the trial date. Interestingly, had these defendants been litigating in the District of New Jersey they would have been obligated to demonstrate “good cause,” where Local Patent Rule 3.7 requires a showing of “good cause” for any party to amend “contentions, disclosures, or other documents required...

Plaintiffs’ Local Patent Rule 3.2(b) Document Production Sufficient to Support an “Invention Date” Predating a Disclosed “Priority Date”

Applying the plain language of the District of New Jersey’s Local Patent Rules, Chief Judge Wolfson recently ruled in Mitsubishi Tanabe Pharma Corp. v. Sandoz Inc., that the plaintiffs were not precluded from asserting an “invention date” derived from their Local Patent Rule 3.2(b) disclosures that differed from the “priority date” expressly disclosed in their Local Patent Rule 3.1(f) contention disclosures. Local Patent Rule 3.1(f) requires that infringement contentions disclose, “[f]or any patent that claims priority to an earlier application, the priority date to which asserted claim is allegedly entitled.” Local Patent Rule 3.2 governs the document production that must accompany Local Patent Rule 3.1 disclosures and Local Patent Rule 3.2(b) requires the production of “[a]ll documents evidencing the conception, reduction to practice, design, and development of each claimed invention, which were created on or before the date of application for the patent in suit or the priority date identified pursuant to L. Pat. R. 3.1(f), whichever is earlier.” An “invention date” and a “priority date” have distinct meanings in patent law. An “invention date” is the date when the inventor conceived the invention and reduced it to practice and the “priority date” is the filing date of the earliest patent application to which the patents-in-suit are entitled. The plaintiffs’ Local Patent Rule 3.1(f) infringement...

USPTO Waives Certain Deadlines in Light of the Coronavirus Outbreak

On March 31, 2020, the United States Patent and Trademark Office (“USPTO”) issued a notice permitting 30-day extensions to the time allowed to file certain patent-related documents and to pay certain required fees. Gibbons previously analyzed the first USPTO coronavirus guidance. For this second guidance, the USPTO determined, under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), that the COVID-19 “emergency has prejudiced the rights of applicants, patent owners, or others appearing before the USPTO in patent matters, and has prevented applicants, patent owners, or others appearing before the USPTO in patent matters from filing a document or fee with the Office.” The USPTO thus provided parties with the ability to extend certain patent deadlines if the party is personally affected by the COVID-19 outbreak. The USPTO notice expressly provides that three Patent Trial and Appeal Board (PTAB) deadlines may be extended for 30 days upon request: a request for rehearing of a PTAB decision; a petition to the Chief Judge under 37 C.F.R. § 41.3; and a patent owner preliminary response in a trial proceeding. “For all other situations, a request for an extension of time where the COVID-19 outbreak has prevented or interfered with a filing before the Board can be made by contacting the PTAB.” Relief under the notice is...

FDA Will Now Provide More Data on 180-Day Exclusivity in the Orange Book

In a recent alert, the FDA announced that effective June 18, 2019, the Agency will publish additional data in the Orange Book Paragraph IV Certifications list. To enhance the already published data, the Orange Book will now include (1) the number of potential first applicants; (2) the 180-day decision date; (3) the date of the “first applicant” approval; (4) the date of first commercial marketing by any first applicant; and (5) the expiration date of the last qualifying patent. According to the FDA, the updated data listing comports with the Agency’s commitment under the Drug Competition Action Plan where the FDA “committed to enhancing efficiency of the development and approval of ANDAs, with the ultimate goal of more approvals.” Historically, the Orange Book Paragraph IV Certifications list has contained relevant information related to 180-day eligibility for generic drug products. Until recently, the listings included the name of the drug product, dosage form, dosage strength(s), the reference listed drug, the New Drug Application Number and the date upon which the first substantially complete application containing a Paragraph IV certification was submitted to the Agency. The new data will provide greater clarity to Hatch-Waxman litigants in a variety of ways. More specifically, with respect to the number of first applicants, the data will provide the number of...

District Court Must Consider Whether the Patentee Must be Joined Before Dismissing the Case for Lack of Statutory Standing

The question of who must join a patent infringement suit often raises interesting questions of rights, obligations, and control of the litigation. In the global marketplace with increased licensing arrangements, the extent of retaining rights can have a direct impact on the viability of a lawsuit and protecting intellectual property. Recently, the Federal Circuit in Lone Star Silicon Innovations v. Nanya Technology provided further clarification on what meets the standing requirement to bring a patent infringement case, and for dismissing a case for lack of standing. In this patent litigation, the asserted patents (twelve in all) were originally assigned to Advanced Micro Devices (AMD). AMD later executed an agreement purporting to transfer “all right, title and interest” in the patents to Lone Star. The transfer agreement, however, imposes several limitations on Lone Star. For example, Lone Star may only assert the patents against “Unlicensed Third Party Entit[ies]” specifically listed in the agreement. To add new entities, Lone Star and AMD both must agree. If Lone Star sues an unlisted entity, AMD has the right, without Lone Star’s approval, to sublicense the patents to the unlisted entity. Further, AMD can prevent Lone Star from assigning the patents, and AMD and its customers can continue to practice the patents. Finally, AMD shares in any revenue Lone Star...
