Apparently Microsoft has a thing for conservative Japan. Just when I thought Microsoft had closed patent cross-licensing deals with every Japanese firm ever to have considered corporate existence, Microsoft surprises me with a deal with Onkyo.

Over two years ago, Microsoft and Novell signed an interoperability deal. Part of this agreement was a patent deal that suggested that Linux infringed on Microsoft's IP. Since then, Microsoft has signed a number more of these deals with various companies, but the Novell one is still the most famous.

Few events have created more fodder for the blogosphere, more fuel for Microsoft critics and more emotional responses than the Microsoft patent deals with Novell, Linspire and Xandros. While putting together a list of things people hate about these deals is easy, generating a list of positive aspects is much harder.

Microsoft issued and spread another wave of propaganda yesterday, calling for more companies to sign patent deals like Novell's

Microsoft and Brother Industries have entered into a broad patent cross-licensing agreement that enables access to each company's respective patent portfolio, including Brother's embedded Linux printing products. Aimed at boosting R&D efforts, the agreement includes compensation paid to Microsoft by Brother, say the companies.

Microsoft and Amazon announced on Monday that the two have entered into a patent cross-licensing deal. As part of the pact, Amazon will pay Microsoft an undisclosed amount of money, though the two sides did not disclose more details

For sometime there, I generally figured that once the next revision of the GPL came about, all of these deals that are being made with Microsoft will eventually be put to bed. I was also delighted to see Mandriva standing against the alleged patent violations that Microsoft brought up time and again.

The Linux community is splitting -- right down the middle, at this point -- over Microsoft's controversial claims that the open source operating system infringes on patents it holds. On June 19, Paris-based Mandriva became the third Linux vendor within five days to say it isn't interested in signing a licensing deal with Microsoft to avoid possible infringement claims.

Microsoft is suing TomTom in part because the guys from Redmond claim that TomTom's use of Linux in its navigation devices has violated three of its file-system related patents. One reason why Microsoft feels it can do this is that it already has patent cross-licensing agreements covering these patents with other Linux-using companies.
