UI War Brewing: Microsoft Multi-Touch Patent App Predates Apple's
Smell the hint of smoke in the air? It actually started when Microsoft announced that a full multi-touch interface would be built into Windows 7. But it's now getting thick as the company posted a fuller description of the new interface, which includes not only single-touch, but multi-touch features. Providing the other half of the friction is Apple's recently-granted broad patent on multi-touch UI technology. But although Apple has indicated its readiness to enforce the patent, facing off against Microsoft could prove the business equivalent of shooting yourself in the foot with a howitzer. Particularly when Microsoft has a multi-touch patent application that predates any of Apple's filings.
