  “13.2.4 The Parties, will use commercially reasonable efforts to file Patent Rights for Improvements as either MAGENTA IP Improvements or as HDPR IP Improvements to the extent reasonably possible, taking into account the requirements of various jurisdictions. Patent Rights may also be filed as Joint IP Rights if the JPC decides that adequate protection for the Compounds and Products in such jurisdiction cannot be achieved only through the filing of Patent Rights directed at MAGENTA IP Improvements and/or at HDPR IP Improvements.  By way of non-limiting example, Patent Rights with respect to Improvements to Amanitin, Linkers, or Amanitin Toxin Constructs would likely be filed as HDPR IP Improvements whereas Patent Rights with respect to Improvements to Products and Compounds against Exclusive Development Targets would likely be Joint IP Rights; provided that in each case taking into account any considerations and possible implications to providing adequate protection in doing so.”

  e.Section 13.5.1 is hereby deleted and replaced with the following:


  “HDPR IP Rights.  HDPR shall, at its sole cost and acting in its sole discretion, be responsible for Handling the Patent Rights included in the HDPR IP Rights and HDPR Improvements. HDPR shall promptly provide MAGENTA with copies of any material official correspondence to or from patent offices regarding the Patent Rights included in the HDPR Improvements. HDPR shall provide MAGENTA with a reasonable opportunity to review and comment on material filings relating to such Patent Rights before such filings are submitted to any relevant patent office or governmental authority, and shall give reasonable, good faith, consideration to comments offered by MAGENTA with respect thereto in any final filings submitted by HDPR to any relevant patent office or governmental authority; provided that HDPR shall have the final decision with respect thereto.  Without limiting the immediately preceding sentence, HDPR shall provide to MAGENTA (i) any draft new first-patent priority application intended for filing, (ii) the draft of any other new application containing data generated under this Agreement (not including continuations or divisionals, but including continuations-in-part) and/or (iii) additional claims to a PCT application or any national equivalent filing thereof,  with respect to (i), (ii) and (iii) to the extent that it constitutes an HDPR Improvement (each a “New HDPR Application”) for review at least [**] before filing.  If such [**] review period cannot be maintained due to upcoming disclosure, as discussed in the JPC according to Section 13.7.2(c) below, the Parties will work together in good faith to review on an expedited basis.  Should HDPR intend not to Handle a Patent Right included in the HDPR IP Rights (solely to the extent that such HDPR IP Rights are reasonably necessary or useful for the discovery, manufacture, development or commercialization of Compounds or Products) or HDPR Improvements in a country in the Territory, it shall promptly advise MAGENTA thereof. At the written request of MAGENTA, HDPR shall, at its sole discretion, either continue to Handle such Patent Right at its own cost or, at no cost and no further consideration execute and deliver any documents as may be legally required to permit MAGENTA to Handle any such Patent Right, and MAGENTA may thereafter Handle any such Patent 

  4

   

   

  

   

  Right at MAGENTA’s own cost (subject to the remainder of this Section 13.5.1) and sole discretion, to the extent that MAGENTA desires to do so. For sake of clarity, HDPR shall use commercially reasonable efforts to maintain any such Patent Right which MAGENTA requested to Handle until responsibility for any such Patent Right has been transferred to MAGENTA (at which point such Patent Rights will be deemed “MAGENTA Handled Patent Rights” hereunder). For clarity, such MAGENTA Handled Patent Rights will continue to be owned by HDPR. If any royalties become due from MAGENTA to HDPR under Section 9.4 with respect to Net Sales of any Product in a country that is Covered by any MAGENTA Handled Patent Rights in such country but is not Covered by any other Patent Rights included in the HDPR IP Rights, HDPR Improvements or Joint IP Rights in such country, (i) HDPR will promptly reimburse to MAGENTA all costs and expenses incurred by MAGENTA in connection with the applicable MAGENTA Handled Patent Rights, and (ii) MAGENTA shall pay to HDPR any such royalties in accordance to the terms and conditions of this Agreement.”

  f.Section 13.5.2 is hereby deleted and replaced by the following:


  “Section 13.5.2   MAGENTA IP Rights.

  	(a) MAGENTA shall, at its sole cost and acting in its sole discretion, Handle all Patent Rights included in the MAGENTA IP Rights, MAGENTA IP Improvements, Joint IP Rights, and Amendment No. 3 Patent Rights; provided that MAGENTA shall provide HDPR with a reasonable opportunity to review and comment on material filings relating to Joint IP Rights and any Amendment No. 3 Patent Rights before such filings are submitted to any relevant patent office or governmental authority and shall give reasonable, good faith, consideration to comments offered by HDPR with respect thereto in any final filings submitted by MAGENTA to any relevant patent office or governmental authority; and further provided that MAGENTA shall have the final decision with respect thereto. Without limiting the immediately preceding sentence, MAGENTA shall provide to the JPC (i) any draft new first-patent priority application intended for filing, (ii) the draft of any other new application containing data generated under this Agreement (not including continuations or divisionals, but including continuations-in-part), and/or (iii) additional claims to a PCT application or any initial national equivalent filing thereof, with respect to (i), (ii) and (iii) to the extent that it constitutes a MAGENTA IP Improvement, a Joint IP Right or an Amendment No. 3 Patent Right (each a “New Application”) for review at least [**] before filing.  If such [**] review period cannot be maintained due to upcoming disclosure, as discussed in the JPC according to Section 13.7.2(c) below, the Parties will work together in good faith to review on an expedited basis. MAGENTA shall promptly provide the JPC with copies of any material official correspondence to or from patent offices regarding the Patent Rights included in the Joint IP Rights or Amendment No. 3 Patent Rights.  In case of a violation by MAGENTA of this Section 13.5.2(a), (i) such violation shall constitute a material breach of the Agreement (without limiting or impacting whether a breach of any other provision of the Agreement would constitute a material breach) and (ii) 

  5

   

   

  

   

  MAGENTA hereby grants to HDPR and HDPR hereby accepts a worldwide, royalty-free, fully paid-up, perpetual, irrevocable, non-exclusive, freely sublicensable (through multiple tiers) license to any Patent Rights filed or prosecuted in violation of this Section 13.5.2(a).  If such breach gives rise to HDPR’s ability to terminate all or a part of this Agreement under Section 18.2.1 as a result of such breach, HDPR shall be required to provide written notice of termination to MAGENTA within [**] after  giving written notice of such breach to MAGENTA according to Section 18.2.1 if HDPR wants to exercise such termination right; for clarity, if HDPR does not deliver such written notice to MAGENTA within such [**] period, HDPR’s right to terminate all or a part of this Agreement as a result of such breach shall expire.  The foregoing remedy for a violation by MAGENTA of this Section 13.5.2(a) shall be non-exclusive and without prejudice to any other rights or remedies HDPR may seek against MAGENTA for such violation; nor does such foregoing remedy alter any of MAGENTA’s rights to dispute such breach or stay such termination if it elects to do so under Section 18.2.1.

  	(b)	Should MAGENTA decide that it does not desire to Handle a Patent Right included in the Joint IP Rights or any of the Amendment No. 3 Patent Rights in a country in the Territory, it shall promptly advise HDPR thereof. At the written request of HDPR, MAGENTA shall, at no cost and no further consideration execute and deliver any documents as may be legally required to effect the assignment of any such Patent Right in such country to HDPR. HDPR may thereafter Handle any such Patent Right at HDPR’s own cost and sole discretion, to the extent that HDPR desires to do so. For sake of clarity, MAGENTA shall use commercially reasonable efforts to maintain any such Patent Right which HDPR requested to Handle until the assignment of any such Patent Right has been effected.”
