As the saying goes, you win some and you lose some. That sentiment may characterize Sirf Technology today. 

On the bad news front, Broadcom says the International Trade Commission yesterday affirmed that Sirf Technology infringes on three GPS-related patents held by Global Locate, a Broadcom subsidiary. The ITC will now decide whether to impose remedies or ban the importation into the U.S. of products with the infringing Sirf patents. In addition, the commission also will review three other patents Broadcom says Sirf is infringing upon.

On the good news front, Sirf said it has signed a mutual non-assertion agreement with Qualcomm to cover each of their patent portfolios. The company said the agreement will help expand the market for location-enabled products, services and content.
