Okla. Stat. tit. 23, § 23-112

Exceptions.

A. No person shall, in connection with the assertion of a

United States patent, send or cause any person to send any written

or electronic communication that states that the intended recipient

or any affiliated person is infringing or has infringed a patent and

bears liability or owes compensation to another person, if:

1. The communication falsely states that litigation has been

filed against the recipient, or threatens litigation if compensation

is not paid or the infringement issue is not otherwise resolved and

there is a consistent pattern of such threats having been issued and

no litigation having been filed;

2. The communication falsely states that litigation has been

filed against the intended recipient or any affiliated person; or

3. The assertions contained in the communication lack a

reasonable basis in fact or law because:

has been held to be invalid or unenforceable in a

final, unappealable or unappealed judicial or

administrative decision,

c. the communication seeks compensation on account of

activities undertaken after the patent has expired, or

license the patent to or enforce the patent

against the intended recipient or any affiliated

person,

(2) the patent number issued by the United States

Patent and Trademark Office alleged to have been

or sale;

electronic communication sent by:

with substantial research, development, production, manufacturing,

processing or delivery of products or materials;

is to facilitate the commercialization of technology developed by an

institution of higher education.
