INTRODUCTION

1. This complaint arises from Defendant’s unlawful infringement of the following 

United States patent owned by Zeroclick: United States Patent No. 7,818,691 (“’691 Patent” or 

“Asserted Patent”).

2. Plaintiff is the owner and assignee of a portfolio of patents containing the inventions 

of Dr. Nes Irvine, a medical doctor who possessed the prescient vision to develop touch-only user 

interface technologies that would enable significant benefits to his medical work and any field 

where users interacted with graphical user interfaces (“GUIs”). Dr. Irvine filed applications that 

eventually became his “Zeroclick” U.S. Patents in the year 2000.

PARTIES

3. Plaintiff Zeroclick, LLC is a Texas limited liability company, having a business 

address at 3610-2 N Josey Lane #223, Carrollton, TX 75007.

4. On information and belief, Defendant Microsoft Corporation is a corporation 

organized under the laws of the State of Washington, with its principal place of business at One 

Microsoft Way, Redmond, Washington 98052.

JURISDICTION AND VENUE

5. This action arises under the patent laws of the United States, Title 35 of the United 

States Code. This Court has original subject matter jurisdiction pursuant to 28 U.S.C. §§ 1331 and 

1338(a).

6. This Court has personal jurisdiction over Defendant in this action because 

Defendant has committed acts within this District giving rise to this action, and has established 

minimum contacts with this forum such that the exercise of jurisdiction over Defendant would not 

offend traditional notions of fair play and substantial justice. Defendant, directly and through 

subsidiaries or intermediaries, has committed and continues to commit acts of infringement in this 

District by, among other things, importing, offering to sell, and selling products that infringe the 

asserted patents.

7. Venue is proper in this District under 28 U.S.C. § 1400(b). Defendant is registered 

to do business in Texas, and upon information and belief, Defendant has transacted business in 

this District and has committed acts of direct and indirect infringement in this District by, among 

other things, making, using, offering to sell, selling, and importing products that infringe the 

Asserted Patents. Defendant has a regular and established place of business in the District, 

including corporate offices at 10900 Stonelake Boulevard, Suite 225, Austin, Texas and a retail

COUNT I

INFRINGEMENT OF U.S. PATENT NO. 7,818,691

8. Plaintiff realleges and incorporates by reference the foregoing paragraphs as if fully 

set forth herein.

9. Plaintiff is the owner and assignee of United States Patent No. 7,818,691 (“the ‘691 

patent”) titled “Zeroclick.” The ‘691 patent was duly and legally issued by the United States Patent 

and Trademark Office on October 19, 2010. Plaintiff is the owner and assignee, possessing all 

substantial rights, to the ‘691 patent. A true and correct copy of the ’691 Patent is attached as 

Exhibit 1.

10. On information and belief, Defendant makes, uses, offers for sale, sells, and/or 

imports certain touch screen computing products (“Accused Products”), such as the Microsoft 

Surface Book 2 13.5, that directly infringe, literally and/or under the doctrine of equivalents, one 

or more claims of the ’691 Patent. 

11. Defendant also knowingly and intentionally induces infringement of one or more 

claims of the ’691 Patent in violation of 35 U.S.C. § 271(b). Through the filing and service of this 

Complaint, Defendant has had knowledge of the ’691 Patent and the infringing nature of the 

Accused Products. Despite this knowledge of the ’691 Patent, Defendant continues to actively 

encourage and instruct its customers and end users (for example, through its user manuals and 

online instruction materials on its website) to use the Accused Products in ways that directly 

infringe the ‘691 Patent. Defendant does so knowing and intending that its customers and end users 

1 See, e.g., https://www.microsoft.com/en-us/about/officelocator/default.aspx?Location=78759; 

https://www.microsoft.com/en-us/store/locations/tx/austin/the-domain/store-11. 

Case 6:20-cv-00423-ADA Document 1 Filed 05/26/20 Page 3 of 5

will commit these infringing acts. Defendant also continues to make, use, offer for sale, sell, and/or 

import the Accused Products, despite its knowledge of the ’691 Patent, thereby specifically 

intending for and inducing its customers to infringe the ’691 Patent through the customers’ normal 

and customary use of the Accused Products.

12. The Accused Products satisfy all claim limitations of one or more claims of the 

’691 Patent. A claim chart comparing independent claim 2 of the ’691 Patent to a representative 

Accused Product, the Microsoft Surface Book 2 13.5, is attached as Exhibit 2.

13. By making, using, offering for sale, selling and/or importing into the United States 

the Accused Products, Defendant has injured Plaintiff and is liable for infringement of the ’691

Patent pursuant to 35 U.S.C. § 271.

14. As a result of Defendant’s infringement of the ’691 Patent, Plaintiff is entitled to 

monetary damages in an amount adequate to compensate for Defendant’s infringement, but in no 

event less than a reasonable royalty for the use made of the invention by Defendant, together with 

interest and costs as fixed by the Court.

15. Defendant’s infringing activities have injured and will continue to injure Plaintiff, 

unless and until this Court enters an injunction prohibiting further infringement of the ’691 Patent, 

and, specifically, enjoining further manufacture, use, sale, importation, and/or offers for sale that 

come within the scope of the patent claims.

PRAYER FOR RELIEF

WHEREFORE, Plaintiff respectfully requests that this Court enter:

a. A judgment in favor of Plaintiff that Defendant has infringed, either literally and/or 

under the doctrine of equivalents, the ‘691 Patent;

b. A permanent injunction prohibiting Defendant from further acts of infringement of

the ’691 Patent;

c. A judgment and order requiring Defendant to pay Plaintiff its damages, costs, 

expenses, and pre-judgment and post-judgment interest for Defendant’s infringement of the ’691

Patent; and

d. A judgment and order requiring Defendant to provide an accounting and to pay 

supplemental damages to Plaintiff, including without limitation, pre-judgment and post-judgment 

interest; 

e. A judgment and order finding that this is an exceptional case within the meaning 

of 35 U.S.C. § 285 and awarding to Plaintiff its reasonable attorneys’ fees against Defendant; and

f. Any and all other relief as the Court may deem appropriate and just under the 

circumstances.

DEMAND FOR JURY TRIAL

Plaintiff, under Rule 38 of the Federal Rules of Civil Procedure, requests a trial by jury of 

any issues so triable by right.
