Introduction
Intra-Cellular Therapies, Inc., a biopharmaceutical company, has been involved in several significant patent litigation cases, one of which is the case against Andrei Iancu, the then-Director of the United States Patent and Trademark Office (USPTO). This article provides a detailed summary and analysis of the litigation in Intra-Cellular Therapies, Inc. v. Matal (1:17-cv-00776).
Background
Intra-Cellular Therapies, Inc. is known for its innovative treatments for complex psychiatric and neurologic diseases, founded on Nobel prize-winning research. The company's product, CAPLYTA® (lumateperone), has been at the center of several patent disputes.
The Patent Application and Initial Rejections
In September 2010, Intra-Cellular Therapies filed a patent application that eventually led to the issuance of the '077 patent. However, the journey to patent approval was not straightforward. In October 2012, the USPTO issued a non-final office action rejecting certain claims under 35 U.S.C. § 103 (obviousness) and § 112 (indefiniteness and lack of written description)[3].
Appeals and Amendments
Intra-Cellular Therapies argued against these rejections without amending the claims. Following a final office action in April 2013 that allowed no claims, the company submitted an "Amendments and Response" on the last day for filing a reply to the final office action. This submission repeated previous arguments and added a new claim. However, the Patent Office issued an Advisory Action indicating that the submission did not overcome the prior rejections under § 103[3].
Further Submissions and Allowance
Intra-Cellular Therapies made a second after-final submission, adopting the examiner's suggestions to amend or cancel certain claims. This submission was successful, and a Notice of Allowance was mailed on August 20, 2013[3].
Patent Term Adjustment Dispute
The dispute in Intra-Cellular Therapies, Inc. v. Matal primarily revolved around the patent term adjustment (PTA) for the '077 patent. In January 2017, the USPTO determined that the patent was entitled to 264 days of PTA due to agency delays, but subtracted 21 days for applicant delay. This deduction was based on the time it took Intra-Cellular Therapies to file its second after-final submission after the response deadline[3].
Federal Circuit Ruling
Intra-Cellular Therapies appealed the USPTO's determination to the Federal Circuit. The court affirmed the USPTO's decision, ruling that the initial response did not constitute a proper "reply" under 37 CFR 1.704(b) because it continued to argue the merits of the final rejections rather than complying with regulatory requirements. The clock for PTA stopped with the second after-final submission, 21 days later[3].
Analysis of the Ruling
The Federal Circuit's decision highlights the importance of adhering strictly to the regulatory requirements for responding to final office actions. Intra-Cellular Therapies' failure to comply with these requirements resulted in a reduction of the patent term adjustment, which could have significant implications for the company's intellectual property protection and market exclusivity.
Implications for Patent Litigation
This case underscores the meticulous nature of patent litigation and the need for precise compliance with procedural rules. Companies involved in patent disputes must ensure that all submissions and responses are timely and meet the specific requirements set by the USPTO to avoid adverse rulings.
Comparison with Other Cases
In contrast to cases where courts have found litigation conduct to be unreasonable or where discovery violations have been significant, Intra-Cellular Therapies, Inc. v. Matal focuses on the technical aspects of patent prosecution. The case does not involve allegations of misconduct or unreasonable litigation conduct, but rather a dispute over procedural compliance and its impact on patent term adjustment[2].
Conclusion
The litigation in Intra-Cellular Therapies, Inc. v. Matal serves as a reminder of the complexities and nuances involved in patent law. The case emphasizes the importance of careful adherence to procedural rules during the patent application and appeal process.
