This jives with the info from RLF web site I posted previously. From this statement it looks like many, if not all, patents are current:
Over the years, Relief Therapeutics has obtained a large number of patented indications for various peptides and proteins of natural origin. Although Relief is conscious that these experimental medicinal products might be beneficial to the patients, its limited resources prevent Relief from developing them further. These programs can be out-licensed to interested companies or organizations. Do not hesitate to contact us.
