Hiro pledges that it will not initiate a lawsuit against any party for infringing a Hiro Patent through activity relating to Free or Open-Source Software, except for Defensive Purposes, as defined below.
Hiro intends this Pledge to be legally binding, irrevocable, and enforceable against Hiro, any subsidiaries or affiliates it controls, and its successors and assigns. Thus, Hiro will require any person or entity to whom it sells, assigns, transfers, or conveys any Hiro Patents to agree, in writing, to abide by the Pledge and to place a similar requirement on any subsequent transferees to do the same.
Definition of Key Terms
“Hiro” means, for purposes of this Pledge, Hiro Systems PBC and any subsidiaries or affiliates that it controls.
"Hiro Patents" means the patents set forth in the section entitled Hiro Patents Covered by the Pledge.
“Defensive Purposes” means an assertion of legal rights against a party who, directly or indirectly, files, maintains, threatens, voluntarily participates in, or has a financial stake in any claim, cross-claim, or counterclaim for infringement of patent or other intellectual property right against Hiro or any other party based upon the development, manufacture, use, sale, offer for sale, lease, license, exportation, importation, or distribution of technologies claimed in the Hiro Patents or invented by Hiro.
“Free or Open-Source Software” means any software that is licensed or otherwise distributed to the public in such a way that satisfies any version of “The Open Source Definition” provided by the Open Source Initiative at opensource.org/osd or any version of “The Free Software Definition” provided by the Free Software Foundation at gnu.org/philosophy/free-sw.html.
“Pledge” means the promises set forth in the section entitled Our Pledge.
This Pledge covers only patents listed in the section entitled Hiro Patents Covered by the Pledge. It excludes patents owned by third parties. Hiro cannot assure that the technologies covered in its patents do not infringe upon the intellectual property rights of any third party. Blockstack PBC makes no representations and disclaims any and all warranties as to the validity or enforceability of the Hiro Patents.
To preserve Hiro’s ability to enforce the Hiro Patents for Defensive Purposes, the Pledge is not a waiver of any patent claims and is not a license, covenant not to sue, or authorization to engage in patented activities or a limitation on remedies, damages, or claims. Except as expressly stated in the Pledge, no rights shall be deemed granted, waived, or received by implication, exhaustion, estoppel, or otherwise. The Pledge is not an indication of the value of an arms-length negotiated license or a reasonable royalty.
Hiro may still enter into license agreements under individually negotiated terms for those who wish to use Hiro technology but cannot or do not wish to rely on this Pledge alone.
