8.2 Improvements. Improvements to existing products or methods which arise in the course of providing Services or use of Equipment under this Agreement will belong to the Party which owns the product or method to which the improvement relates, regardless of which Party’s personnel suggested, developed or contributed to the improvement, and regardless of the extent of any such contribution by the non-owning Party. The foregoing shall apply even if the improvement is separately patentable as a new invention.

8.3 Inventions. Any new inventions which arise in the course of providing Services or using Equipment under this Agreement and which are not improvements to the existing products or methods of one Party or the other will belong to the Party whose personnel originated the new invention.
