Q: how do I contact this company for a licence to one of these patents

A: To answer your question, we need to break it down into a few steps:

1. Patent verification:

First, we need to confirm that the use of Beta-Hydroxybutyrate (BHB) for increasing ketone bodies is indeed patented. Without specific patent information, I can't verify this claim. However, if you have identified a specific patent, that's a good starting point.

2. License requirement:

If there is a valid patent covering the use of BHB for increasing ketone bodies, and you want to sell a product using this method, you would likely need a license from the patent holder. This is correct.

3. Contacting the patent holder:

To discuss a license, you would need to contact the patent holder or their representative. Here's how you can proceed:

a. Identify the specific patent(s) you need to license.

b. Look up the patent information using a patent database like Google Patents or the USPTO website.

c. Find the current assignee (owner) of the patent. This may be different from the original inventor if the patent has been sold or transferred.

d. Search for the company's contact information online.

e. Reach out to their legal or licensing department to discuss licensing options.

4. Alternative approaches:

If obtaining a license proves difficult or expensive, you might consider:

- Exploring alternative formulations that don't infringe on the patent

- Waiting for the patent to expire (patents typically last 20 years from the filing date)

- Consulting with a patent attorney to determine if there are ways to work around the patent

Remember that patent law can be complex, and it's often advisable to consult with a patent attorney or intellectual property lawyer before proceeding. They can help you navigate the licensing process and ensure you're not inadvertently infringing on any patents.
