Developments include:

2. Patent misuse from using a patent to cause another patentee to refuse to license its patent;

3. Quanta precludes enforcement of a post-sale use condition, such as a single-use restriction;

4. Claims to artificially reducing a biological activity lacked adequate written description where specification failed to adequately describe how the reduction would be attained;

5. Obviousness-type double patenting for a method of making a product in view of a prior patent claiming the product assessed based on the methods of making known at the time the method application is filed;

6. Canceling independent claim and rewriting dependent claim in independent form creates presumption of surrender even though additional limitations had to be added to overcome prior art;

7. Patentee drug manufacturer did not have a duty to preserve electronic data before receiving its first Paragraph IV certification letter;

8. USPTO announces pilot patent prosecution highway with German patent office and extends pilot program with Australian patent office.
