Re: Intellectual Property Rights of GTX Corp.
Dear Mr. Wolfley:
This law firm represents GTX Corp.("GTX")in its intellectual property enforcement
matters. GTX has discovered that Playsaurus, Inc.("Playsaurus") is facilitating the acquisition
and utilization of electronic tokens by consumers through its payment platform in violation of
GTX's intellectual property rights. In facilitating such transactions via its server platform, it
appears that Playsaurus is inducing infringement of at least one claim of GTX's U.S. Patent No.
7,177,838 (see Exhibit A). So that you can better understand GTX's position, a draft Complaint
for patent infringement is enclosed for your review (see Exhibit B).
In view of the foregoing, GTX demands that Playsaurus immediately cease and desist
from facilitating the acquisition and utilization of electronic tokens by consumers through
Playsaurus's payment platform in a manner that violates any intellectual property rights of GTX.
We are hopeful that Playsaurus will stop any infringing actions and request that you
confirm that Playsaurus has done so within ten (10) days of receipt of this letter. To provide you
with a path forward, GTX is currently offering Playsaurus a non-exclusive license to its '838
patent, for a fully paid up license fee of $35,000 through the remaining term of the patent. We
urge you to secure a license by the end of the ten (10) day period to avoid costly litigation as this
offer is extended for only a limited period of time.
The information contained herein and included within the enclosed draft complaint is not
exhaustive and should not be construed as a waiver of any of GTX's rights and remedies at law
or in equity, and GTX hereby reserves all such rights without prejudice.
Sincerely,
Enclosures
