The Wisconsin Alumni Research Foundation (WARF) alleges that Intel has infringed on copyrights with the inclusion of patented technology into its Intel Core 2 Duo products without informing WARF or seeking to license the invention. WARF says the successful Intel platform is infringing its United States Patent No. 5,781,752, entitled "Table Based Data Speculation Circuit for Parallel Processing Computer."

WARF wants judgments to recognize the infringement, to permanently enjoin and restrain Intel from further infringement, to acknowledge the willful character of Intel's alleged infringement, to award damages equal or greater than the alleged royalties, as well as the payment of all legal fees brought about by the trial.

The complaint was filed in U.S. District Court for the Western District of Wisconsin. What WARF says is that its 1998 patent, developed by four researchers at the UW-Madison, has been deliberately used by Intel for its own profit.

"The technology significantly enhances opportunities for instruction level parallelism in modern processors, thereby increasing their execution speed," states Michael Falk, WARF general counsel. Attached to the filing, WARF put the Exhibit A, a copy of the 1998 patent.

"We were in discussions with WARF for more than a year on this issue. However [we] did not expect this suit," Intel spokesman Chuck Mulloy said. However, WARF said it has been indeed in discussions with Intel, but the CPU giant was apparently not interesting in settling the matter out of court.

The Core 2 brand refers to a range of Intel's consumer 64-bit dual-core and MCM quad-core CPUs with the x86-64 instruction set, in production since 2006. It comes in single (Solo), dual (Duo) or Quad core-CPUs (actually 2x2). The Core 2 lineup reunified the laptop and desktop CPU lines divided into the Pentium 4, D, and M brands, while simultaneously returned to lower clock speeds.

WARF was established in 1925 and was the first university-based technology transfer office.
