Will Amazon’s Tablet Raise Any Patent Issues?

While most of the attention surrounding Amazon’s about-to-be-introduced tablet is around its feature set, it will also be interesting to see if the device raises any patent issues.

Oracle, Microsoft and Apple have all sued over Android, albeit in different ways. Oracle has sued Google directly, while Microsoft and Apple have sued particular hardware makers.

Microsoft and Apple both declined to comment ahead of any product introduction by Amazon. However, Microsoft’s deal with Samsung — and its related comments — reiterate the company’s position that it believes it is owed royalty revenue on each Android device sold.

Also, Microsoft and Amazon do have a patent deal covering the existing Kindle line and Amazon’s Linux-based servers.

The devil, of course, is in the details of just how Amazon does and doesn’t use Android. And there is always the question of what deals might quietly be in place, and which relevant patents Amazon might hold that it can claim are being infringed by any potential litigant.
