Changes in patent law in the United States and other jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our products.

Changes
in either the patent laws or in interpretations of patent laws in the United States or other countries or regions may diminish the value of our intellectual property rights. We cannot predict the breadth of claims that may be allowed or enforced in
our patents or in third-party patents. We may not develop additional proprietary products, services, methods and technologies that are patentable.

Under the
Leahy-Smith America Invents Act, assuming that certain requirements for patentability are met, the first inventor to file a patent application will be entitled to the patent on an invention regardless of whether a third party was the first to invent
the claimed invention. Prior to March 16, 2013, in the United States, the first to invent the claimed invention was entitled to the patent, while outside the United States, the first to file a patent application was entitled to the patent. A
third party that files a patent application in the USPTO on or after March 16, 2013, but before us, could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by such third party,
requiring us to be cognizant of the time from invention to filing of a patent application. Since patent applications in the United States and most other countries are confidential for a period of time after filing or until issuance, we cannot be
certain that we were the first to either (i) file any patent application related to our products or (ii) invent any of the inventions claimed in our patents or patent applications.

The America Invents Act also affects the way patent applications are prosecuted and patent litigation. The Act allows third-party submission of prior art to the USPTO
during patent prosecution or post-grant proceedings, including post-grant review,inter partes review and derivation proceedings, to attack the validity of a patent. Because of a lower evidentiary standard in USPTO proceedings
compared to the evidentiary standard in U.S. federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a

USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence might not be sufficient to invalidate the claim if presented in a district court action.
Accordingly, third parties may attempt to use the USPTO proceedings
