The products in the preceding list, including all variations, editions, and applications of the 

foregoing, and all products and apparatuses of Verizon similar to the foregoing that include the 

claimed elements are the ’613 Accused Instrumentalities.

P.R. 3-1(C): CLAIM CHARTS

Headwater’s analysis of Verizon’s products and apparatuses is based upon information that is 

publicly available and based on Headwater’s own investigation prior to any discovery in this 

action. 

While the publicly available information constitutes evidence of the methods and apparatuses 

used by Headwater in the Accused Instrumentalities, direct evidence of the actual apparatuses and 

methods are at times not publicly available. Accordingly, these infringement contentions are based 

on the available public information, analysis, and reasonable inferences drawn from that 

information.

Headwater reserves the right to amend or supplement these disclosures for any of the 

following reasons (along with any other reason that may be permitted under the court’s rules and 

orders):

(1) Verizon provides evidence of the apparatuses and methods used in the Accused 

Instrumentalities;

Case 2:23-cv-00352-JRG-RSP Document 83-2 Filed 09/05/24 Page 9 of 14 PageID #: 6120
9

(2) The Asserted Claims may include elements that involve features that are implemented by 

hardware structures and logic and Headwater’s current positions on infringement are set 

forth without the benefit of access to Verizon’ssource code, schematics, drawings, or other 

proprietary specifications or information, which cannot be obtained through publicly 

available information, for the Accused Instrumentalities. Therefore, it may be necessary 

for Headwater to supplement its positions on infringement after a complete production of 

such proprietary specifications or information by Verizon;

(3) Headwater’s position on infringement of specific claims will depend on the claim 

constructions adopted by the Court. Because said constructions have not yet occurred, 

Headwater cannot take a final position on the bases for infringement of the Asserted 

Claims; and

(4) Headwater’s investigation and analysis of Verizon’s Accused Instrumentalities are based 

upon information made publicly available by Verizon and by Headwater’s own 

investigations. Headwater reserves the right to amend these contentions based upon 

discovery of non-public information that Headwater anticipates receiving from Verizon

during discovery.

Attached as Exhibits A through D, and incorporated herein in their entirety, are charts 

identifying where each element of the Asserted Claims of the ’541, ’543, ’042, and ’613 patents 

are found in the Accused Instrumentalities.

Unless otherwise indicated, the information provided that corresponds to each claim element 

is considered to indicate that each claim element is found within each of the different variations, 

versions, editions, and applications of each respective Accused Instrumentalities.

P.R. 3-1(D): LITERAL INFRINGEMENT AND DOCTRINE OF EQUIVALENTS

With respect to the patents at issue, Headwater contends that each element of each Asserted 

Claim is literally present. To the extent that Verizon identifies elements of the Asserted Claims that 

it contends are not literally present in the Accused Instrumentalities, Headwater contends that such 

elements are present under the doctrine of equivalents.

P.R. 3-1(F): IDENTIFICATION OF INSTRUMENTALITIES PRACTICING THE 

CLAIMED INVENTION

The ItsOn software may incorporate or reflect the claims of the Asserted Patents. Headwater

reserves the right to supplement this response should further investigation, discovery, or the court’s 

claim construction rulings make such supplementation appropriate.

P.R. 3-2: DOCUMENT PRODUCTION ACCOMPANYING DISCLOSURE

P.R. 3-2(A) DOCUMENTS

Headwater is presently unaware of any documents that evidence any discussion with,

disclosure to, or other manner of providing to a third party, or sale of or offer to sell, any of the 

inventions claimed in the patents in suit prior to their respective application dates.

A diligent search continues for documents, and Headwater reserves the right to supplement 

this response.

P.R. 3-2(B) DOCUMENTS

practice, design, or development of the claimed inventions, which were created on or before the

A diligent search continues for documents, and Headwater reserves the right to supplement 

this response.
