The OpenGL Application Programming Interface(API), a graphics standard found on most modern desktops is, among other things, a means of utilizing the 3D hardware acceleration provided by the video card and a cross platform graphics standard. Microsoft however, have recently laid claim to technology which is vital to OpenGL. Back in early March Microsoft had first mentioned that they had "possible claims" on a technology called vertex programming. Vertex programming is essential in giving developers more control over 3D effects. Microsoft's claims, at the time, had caused great concern among members of the OpenGL Architectural Review Board (ARB), the governing body of the specification. Microsoft later went on to claim Intellectual Property (IP) rights on a technology called fragment shading. According to early Microsoft claims they are willing to license their IP under reasonable and nondiscriminatory terms. What exactly that means however, is unclear. What most experts claim is that if Microsoft have some claim on these technologies then the standard will be at their mercy. They will easily be able to finish it off by asking for excessive loyalties. Considering Microsoft's acquisitions of IP's from SGI, Nvidia, ATI, Intel and others it is quite possible that their claims may be valid. Whether they can actually use IP's acquired in that manner, is a point which still remains unclear.
Many suggest that there is a distinct possibility that this claim may lead to OpenGL becoming a specification restricted to MS and its partners.
