Every so often, materials containing unsolicited intellectual property (IP) is received by businesses. They may be a letter regarding an idea, actual inventions, or other materials.
Despite urban myths, these materials aren't a gift. You can't use the materials without the legal right to do so.
All intellectual property is covered by international law.
All intellectual property is highly sensitive, legally.
The copyright owner retains ownership unless formally assigned to someone else.
You have to deal with the situation defensively, for legal reasons. Some IP owners want acknowledgement of receipt of their materials, for obvious reasons. Just to complicate matters, many aren't too sure of their own rights.
The problem is you've been sent the material, either as a commercial proposition, a suggestion, or out of the blue as a sales pitch.
The simplest option is to regard the materials as advertising for a product, and make your decision regarding their merits on that basis.
You can deal with both the IP and acknowledgement simply, in one letter.
If you wish to reject or consider the concept further, it's not necessary to go into detail.
Note: It's strongly advised if you wish to consider the IP that no formal commitments are made without discussion with the IP owner.
