angry tapir writes "Oracle has suffered a setback in its lawsuit accusing Google of patent infringement and copyright violation in its Android operating system: The U.S. Patent and Trademark Office has rejected one of Oracle's Java-related patents — although it did uphold another. In the latest developments, the PTO on Nov. 9 upheld the claims in Oracle's patent number 6,061,520, and on Nov. 18 it rejected the claims in patent number 7,426,720. Florian Mueller, author of the FOSS Patents blog, asserted in July that the so-called '720 patent is "strategically very important" and "may very well be" the most important patent in the case. That's because it is the "youngest" of the patents at issue; it doesn't expire until 2025, while the other patents all expire in 2018 or earlier."
