-- First in new family of EXPAREL patents --
-- Expands EXPAREL intellectual property and provides protection into 2044 --
PARSIPPANY, N.J., Dec. 03, 2024 (GLOBE NEWSWIRE) -- Pacira BioSciences, Inc. (Nasdaq: PCRX), the industry leader in the delivery of innovative, non-opioid pain therapies, today announced the receipt of U.S. Patent No. 12,156,940 (the ‘940 patent) from the U.S. Patent and Trademark Office (the U.S. PTO). The ‘940 patent, entitled “Manufacturing of Bupivacaine Multivesicular Liposomes” protects the chemical composition of EXPAREL® (bupivacaine liposome injectable suspension). This patent is the first patent from a new family of patents related to EXPAREL produced by the company’s enhanced large-scale manufacturing process in San Diego, which received approval from the U.S. Food and Drug Administration in February 2024. The company expects the ‘940 patent to provide protection into July 2044.
“This new patent highlights our commitment to building a broad portfolio of intellectual property to protect our EXPAREL franchise by expanding its patent life into 2044,” said Frank D. Lee, chief executive officer of Pacira BioSciences. “This patent, the first of a new family of patents, underscores Pacira’s deep manufacturing expertise and the team’s commitment to innovation. We firmly believe we have a strong portfolio of intellectual property and the EXPAREL franchise is well protected on multiple levels.”
Pacira will submit the ‘940 patent for listing in the FDA Approved Drug Products with Therapeutic Equivalence Evaluations (the Orange Book). Patents that are eligible for Orange Book listing are those that have claims covering the active ingredient, the drug product (formulation and composition) or the approved method of use. The company continues to prosecute patent applications and anticipates additional patents are forthcoming.
Commitment to Protecting EXPAREL Franchise
With the issuance of the ‘940 patent, the company intends to file a patent infringement lawsuit against Jiangsu Hengrui Pharmaceuticals Co. LTD., and its U.S. distributor, Fresenius Kabi USA, LLC.
A separate lawsuit is advancing against eVenus Pharmaceutical Laboratories, Inc., its China-based parent company, Jiangsu Hengrui, and Fresenius for infringement of U.S. Patent No. 11,819,574 (the ‘574 patent) in the U.S. District Court for the District of New Jersey. Pacira is also pursuing an appellate review at the Federal Circuit for the New Jersey Court’s finding that the company’s U.S. Patent No. 11,033,495 (the ‘495 patent) is not valid. To be successful commercially, eVenus, Jiangsu Hengrui, and Fresenius will have to overcome each of Pacira’s patents.
Expansion of Erucic Acid Family of Patents
The U.S. PTO recently issued U.S. Patent Nos. 12,151,024 (the ‘024 patent) and 12,144,890 (the ‘890 patent). The ‘024 and ‘890 patents belong to the ‘574 and ‘495 family of patents and are listed in the Orange Book with an expiration date of January 21, 2041.
