Pentax has no glass works, which Tokina and Hoya do.
To the best of my knowledge Pentax used to be a part of Asahi Optical.Co, a Japanese optical glass manufacturer. Though these days Just about every lens manufacturer get their glass blanks from external sources: Hoya,Schott,Edmund..etc..etc

Who makes the parts for FA lenses and who assembles them?

Certainly Pentax has no glass works, which Tokina and Hoya do.
Not the point, we were discussing rights. Manufacturing a glass element doesn't give you any claim on the design.

I think most new buyers don't want to " chase " glass for lack of a better term. If they did, then the other big 2 would be less popular and Pentax more popular.
Being able to "chase" vintage glass was one of the reasons I chose to go Pentax over the other two.

They are one in the same. Asahi Optical brought out a camera line called Pentax. In time they adopted Pentax as the company name. Initially they were a lens design house.

QuoteQuote:
The company that would become Pentax was founded in 1919 as Asahi Kōgaku Kōgyō G.K. (旭光学工業㈾). It was originally an optical company, beginning by making glasses under the Aoco brand (presumably the acronym of Asahi Optical Company), and made its first Aoco projection lens in 1923.[1] It began to produce camera lenses in the early 1930s, under the management of the CEO Kajiwara Kumao (梶原熊雄) and his closest collaborator Matsumoto Saburō (松本三郎).[2] These lenses were not marked as made by Asahi, and were produced for various camera models made by other makers. From 1933, the company produced Optor and meniscus achromat lenses designed at Rokuoh-sha for Konishiroku models. From the mid-1930s to the end of World War II, the company was also the main supplier of Molta, then Chiyoda Kōgaku Seikō (predecessors of Minolta), whose cameras were equipped with Coronar and Promar lenses.[3]

The company changed status in 1938, becoming Asahi Kōgaku Kōgyō K.K. (旭光学工業㈱) or Asahi Optical Co. based in Tokyo.[4] It would keep this name until it became Pentax Corporation (ペンタックス㈱) in 2002.
