Shockwave Announces Decisions From the U.S. Patent and Trademark Office on Inter Partes Review Proceeding

SANTA CLARA, Calif., July 08, 2020 (GLOBE NEWSWIRE) -- Shockwave Medical, Inc. (NASDAQ: SWAV), a pioneer in the development of Intravascular Lithotripsy (IVL) to treat complex calcified cardiovascular disease, announced today that the company received the initial rulings related to two of the inter partes review (IPR) cases that were initiated by Cardiovascular Systems, Inc. (CSI).

In December 2018, CSI filed petitions for IPR with the Patent Trial and Appeal Board (PTAB) of the U.S. Patent Office (USPTO) to challenge the validity of three of Shockwave’s issued patents. CSI asked the PTAB to reconsider the original decision of the USPTO to issue those patents and asked that all claims of each patent be invalidated.

The PTAB ruled today that a key claim in U.S. Patent No 8,956,371 (the ‘371 patent) is valid.  This claim is generally directed to a device that creates shockwaves inside of a balloon catheter that is delivered over a guidewire.

Further, the PTAB ruled today that some claims of the U.S. Patent No 8,956,371 are invalid and that all claims of U.S. Patent No 8,728,091 (the ‘091 patent) are invalid.  Shockwave does not agree with the ruling that these claims are invalid.  The IPR decisions are appealable to the U.S. Court of Appeals for the Federal Circuit, and Shockwave remains committed to prosecuting and protecting its patent portfolio to the fullest extent possible.

All claims of the ‘371 and the ‘091 patents remain valid and enforceable until appeals have been exhausted and Shockwave is not prohibited from selling or continuing to develop its IVL technologies.

“We are very pleased that the court validated claim 5 of our ‘371 patent, which protects the broad embodiment of our IVL technologies.  Specifically, claim 5 describes a device that is delivered over a guidewire and generates shockwaves with electrodes inside of a balloon catheter.  We believe that any viable, much less commercially viable, IVL device must contain these elements,” stated Doug Godshall, President and Chief Executive Officer of Shockwave Medical. “While we disagree with the other invalidity findings of the PTAB, we believe we have strong arguments supporting the validity of all claims of both our ‘371 and our ‘091 patents and we intend to appeal this decision with the expectation that we will prevail in our appeal. We believe that our robust portfolio of 40 issued U.S. patents and 50 issued foreign patents captures and protects the truly unique and sophisticated IVL technology that has already helped over 30,000 patients with severely calcified arteries. Our business and pipeline remain compelling, our customer support is strong, and we remain highly committed to the continued advancement of IVL as a treatment for calcified cardiovascular disease.”
