Kyphon Receives Additional Broad U.S. Patent for Kyphoplasty Method Through 2014

SUNNYVALE, Calif., May 1 (HSMN NewsFeed) -- Kyphon Inc. (Nasdaq: KYPH ) today announced that it has expanded its intellectual property coverage over kyphoplasty, the minimally invasive procedure for treating spinal fractures caused by osteoporosis or cancer that Kyphon pioneered in the late 1990s, with issuance of U.S. Patent No. 6,981,981, a method patent covering various aspects of performing the procedure.

More specifically, the '981 patent discloses and claims, among its various embodiments, a method concerning introducing an expandable device into a vertebral body, expanding the device to selectively compact a region of cancellous bone inside the vertebra, and then filling the compacted region. The '981 patent is not expected to expire until 2014.

"We believe the '981 patent significantly extends our patent coverage for key aspects of the fundamental method of performing kyphoplasty," said Richard Mott, Kyphon's president and chief executive officer. "We also believe the issuance of our recent U.S. patents, including the '981 patent, significantly bolsters our existing portfolio and reflects both our continuing commitment to technological innovation and our constant efforts to aggressively pursue patent protection in our core markets in both the U.S. and abroad," Mott concluded.

Other recent patent issuances bring to over 130 the number of patents and patent applications in Kyphon's U.S. portfolio. Corresponding patent filings for many of these have also been made in many foreign jurisdictions, including in select countries in Europe and Asia.
