The U.S. Patent and Trademark Office has endorsed a Web-browsing patent that Microsoft is accused of infringing, dealing a setback to the software company.
In a decision unveiled Wednesday, the office reconfirmed a patent held by Eolas Technologies that allows interactive content to be embedded in a Web site, which is a common practice on the Internet. Eolas is a spin-off of the University of California.
According to a news release from the university, the patent office completed a “re-examination process” on the original patent, which was published in November 1998, and plans to issue a re-examination certificate to uphold its validity.
“We are gratified that the patent office’s re-examination has validated its original evaluation of the University’s unique contribution to the technology, which fuels the Internet,” said James Holst, general counsel for the University of California, in the release. “This decision ensures that the patent rights of the public institution that developed this technology, a significant innovation with wide-reaching public benefits and use, will be protected.”
In a statement, Microsoft said it is studying the patent office’s decision but still plans to present its side of the argument at the retrial as scheduled. “We are confident we will achieve a successful resolution,” the company said.
