7.	PATENT PROVISIONS

7.1

Filing, Prosecution and Maintenance of Patents

RENOVIS agrees to file, prosecute and maintain in the Territory, upon appropriate consultation with MERCK, the RENOVIS Patent Rights licensed to MERCK under this Agreement; provided, however, with respect to Joint Information and Inventions that are not Improvements to RENOVIS Patent Rights or RENOVIS Technology, MERCK shall have the first right to file patent applications for such Joint Information and Inventions. With respect to RENOVIS Information and Inventions, RENOVIS may elect not to file and if so MERCK shall have the right to file patent applications. In such event, RENOVIS shall execute such documents and perform such acts at RENOVIS’ expense as

may be reasonably necessary to effect an assignment of such Patent Rights to MERCK in a timely manner to allow MERCK to continue such prosecution or maintenance. In each case, the filing Party shall give the non-filing Party an opportunity to review the text of the application before filing, shall consult with the non-filing Party with respect thereto, and shall supply the non-filing Party with a copy of the application as filed, together with notice of its filing date and serial number. RENOVIS shall keep MERCK advised of the status of the actual and prospective patent filings and upon the request of MERCK, provide advance copies of any papers related to the filing, prosecution and maintenance of such patent filings. RENOVIS shall promptly give notice to MERCK of the grant, lapse, revocation, surrender, invalidation or abandonment of any Patent Rights licensed to MERCK for which RENOVIS is responsible for the filing, prosecution and maintenance. With respect to all filings hereunder, the filing Party shall be responsible for payment of all costs and expenses related to such filings.

7.2

Option of MERCK to Prosecute and Maintain Patents

RENOVIS shall give notice to MERCK of any desire to cease prosecution and/or maintenance of RENOVIS Patent Rights on a country by country basis in the Territory and, in such case, shall permit MERCK, at its sole discretion, to continue prosecution or maintenance of such Patent Rights at its own expense. If MERCK elects to continue prosecution or maintenance or to file based on RENOVIS’ election not to file pursuant to Section 7.1 above, RENOVIS shall execute such documents and perform such acts at RENOVIS’ expense as may be reasonably necessary to effect an assignment of such Patent Rights to MERCK in a timely manner to allow MERCK to continue such prosecution or maintenance. Any patents or patent applications so assigned shall not be considered Patent Rights.

7.3

Interference, Opposition, Reexamination and Reissue

(a)

RENOVIS shall, within ten (10) days of learning of such event, inform MERCK of any request for, or filing or declaration of, any interference, opposition, or reexamination relating to Patent Rights. MERCK and RENOVIS shall thereafter consult and cooperate fully to determine a course of action with respect to any such proceeding. MERCK shall have the right to review and approve any submission to be made in connection with such proceeding.

(b)

RENOVIS shall not initiate any reexamination, interference or reissue proceeding relating to RENOVIS Patent Rights without the prior written consent to MERCK, which consent shall not be unreasonably withheld.

(c)

In connection with any interference, opposition, reissue, or reexamination proceeding relating to RENOVIS Patent Rights, MERCK and RENOVIS

will cooperate fully and will provide each other with any information or assistance that either may reasonably request.

(d)

RENOVIS shall bear the expense of any interference, opposition, reexamination, or reissue proceeding relating to RENOVIS Patent Rights.

7.4

Enforcement and Defense

(a)

RENOVIS shall give MERCK notice of either (i) any infringement of Patent Rights, or (ii) any misappropriation or misuse of RENOVIS Know-How, that may come to RENOVIS’ attention. MERCK and RENOVIS shall thereafter consult and cooperate fully to determine a course of action, including but not limited to the commencement of legal action by either or both MERCK and RENOVIS, to terminate any infringement of Patent Rights or any misappropriation or misuse of RENOVIS Know-How. However, RENOVIS, upon notice to MERCK, shall have the first right to initiate and prosecute such legal action at its own expense and in the name of RENOVIS and MERCK, or to control the defense of any declaratory judgment action relating to Patent Rights or RENOVIS Know-How. RENOVIS shall promptly inform MERCK if it elects not to exercise such first right and MERCK shall thereafter have the right to either initiate and prosecute such action or to control the defense of such declaratory judgment action in the name of MERCK and, if necessary, RENOVIS. Each Party shall have the right to be represented by counsel of its own choice.

(b)

In the event that RENOVIS elects not to initiate and prosecute an action as provided in paragraph (a), and MERCK elects to do so, the costs of any agreed-upon course of action to terminate infringement of RENOVIS Patent Rights or misappropriation or misuse of RENOVIS Know-How, including without limitation the costs of any legal action commenced or the defense of any declaratory judgment, shall be shared equally by RENOVIS and MERCK.

(c)

For any action to terminate any infringement of Patent Rights or any misappropriation or misuse of RENOVIS Know-How, in the event that MERCK is unable to initiate or prosecute such action solely in its own name, RENOVIS will join such action voluntarily and will execute and cause its Affiliates to execute all documents necessary for MERCK to initiate litigation to prosecute and maintain such action. In connection with any action, MERCK and RENOVIS will cooperate fully and will

provide each other with any information or assistance that either may reasonably request. Each Party shall keep the other informed of developments in any action or proceeding, including, to the extent permissible by law, the consultation and approval of any settlement negotiations and the terms of any offer related thereto.

(d)

Any recovery obtained by either or both MERCK and RENOVIS in connection with or as a result of any action contemplated by this section, whether by settlement or otherwise, shall be shared in order as follows:

(i)

the Party which initiated and prosecuted the action shall recoup all of its costs and expenses incurred in connection with the action;

(ii)

the other Party shall then, to the extent possible, recover its costs and expenses incurred in connection with the action; and

(iii)

the amount of any recovery remaining shall then be allocated between the Parties on a pro rata basis taking into consideration the relative economic losses suffered by each Party.

(e)

RENOVIS shall inform MERCK of any certification regarding any Patent Rights it has received pursuant to either 21 U.S.C. §§355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV) or it successor provisions or any similar provisions in a country in the Territory other than the United States and shall provide MERCK with a copy of such certification within five (5) days of receipt. RENOVIS’ and MERCK’s rights with respect to the initiation and prosecution of any legal action as a result of such certification or any recovery obtained as a result of such legal action shall be as defined in paragraphs 7.4(a)-(d) hereof; provided, however, the RENOVIS shall exercise its first right to initiate and prosecute any action and shall inform MERCK of such decision within ten (10) days of receipt of the certification, after which time MERCK shall have the right to initiate and prosecute such action.

7.5

Patent Term Restoration

The Parties hereto shall cooperate with each other in obtaining patent term restoration or supplemental protection certificates or their equivalents in any country in the Territory where applicable to Patent Rights. In the event that elections with respect to obtaining such patent term restoration are to be made, MERCK shall have the right to make the election and RENOVIS agrees to abide by such election.
