ASSIGNMENT OF INVENTIONS.
(a) In addition to the foregoing, I hereby assign and transfer to the Company my entire right, title and interest in and to all Inventions, whether or not patentable, and whether or not reduced to practice, made, learned or conceived by me (whether alone or jointly with others) during the period of my employment with the Company which relate in any manner at the time of conception to the actual or demonstrably anticipated research or product development by the Company or to its business, or result from or are suggested by any task assigned to me or any work performed by me for or on behalf of the Company. I agree that all such Inventions shall be the sole and exclusive property of the Company and its assigns, and the Company and its assigns shall be the sole owners of all Inventions and any and all patents, copyrights and other proprietary rights related thereto; provided, however, that I hereby acknowledge and agree that this Agreement does not require assignments of an Invention which qualifies fully and expressly for protection under Section 2870 of the California Labor Code.
(b) If I have any right or rights to Inventions that cannot be assigned to the Company or waived by me, I unconditionally grant to the Company during the term of such rights, an exclusive, irrevocable, perpetual, worldwide, fully paid and royalty-free license, with rights to sublicense through multiple levels of sublicenses, to use, reproduce, publish, create derivative works of, market, advertise, distribute, sell, publicly perform and publicly display and otherwise exploit by all means now known or later developed, such Inventions.
