JOINT NOTICE REGARDING ADDITIONAL AGREEMENTS

Plaintiff Headwater Research LLC (“Headwater”) and Defendants Samsung Electronics 

Co., Ltd. and Samsung Electronics America, Inc. (collectively, “Samsung”) file this Joint Notice 

Regarding Additional Agreements: 

1. To resolve Samsung’s MIL No. 1, the parties stipulate to the following: A party 

shall not present evidence, testimony, or argument that another party’s fact witness has not read 

the patents-in-suit or formed opinions regarding the patents-in-suit unless the witness was 

designated on such topics or if a given witness gives testimony at trial regarding those topics; and 

shall not present any argument, evidence, or testimony suggesting that a party’s corporate 

representative at trial is obligated to prepare on any particular topic or is charged with knowledge 

of others within the company unless said representative was previously designated as a 30(b)(6) 

witness on said topic.

2. To resolve Headwater’s MIL No. 1, Samsung stipulates to the following: Samsung 

stipulates to not present evidence or argument regarding any alleged breach of ethical or fiduciary

duties, allegations of improper shifting of funds, embezzlement, threats, or violations of Bar rules, 

including in the context of determining an appropriate damages amount. Samsung further 

stipulates (1) not to introduce testimony, evidence, or argument regarding the amount of offers 

from Qualcomm or Fortress, and (2) not to offer speculation as to why the InterDigital Letter of 

Intent was not consummated. To be clear, Samsung understands this stipulation to permit full 

discussion and use of other evidence relating to the InterDigital Letter of Intent.

3. To resolve the parties’ dispute regarding the procedure for playing deposition video 

clips of witnesses testifying in Korean (see Dkt. 280, at 18), the parties stipulate to the following: 

The parties agree that for any translated depositions, the jury will be shown the question in English, 

the answer in Korean, and the translation of the answer in English, and the time to play all of those 

will be attributed to the party who designated, or counter-designated, that particular testimony.

4. Parties have reached agreement on stipulations regarding representative products

and will provide the language of those stipulations for inclusion in the juror notebooks for trial, 

pursuant to the Court’s instructions during the December 16, 2024 initial pre-trial conference.
