" "I don't mind competing against Intel, but I'd rather not compete
against our own technology," Digital CEO Robert Palmer said. "The time
has come for these unlawful practices to stop."

The patents included in the lawsuit relate to Digital's cache
management, branch prediction, and instruction-processing technology
within the Alpha processor. Patents covering these areas were issued to
Digital between 1988 and 1996.

The lawsuit would stop Intel from using Digital's technology in current
and future chip introductions, according to a company statement, and
seeks an injunction and monetary damage for the patent infringement.

And as a follow-up - 6 months later: October, 1997
< https://www.cnet.com/news/intel-digital-settle-suit/>
" The broad-based agreement includes the sale of Digital's semiconductor
manufacturing operations to Intel for about $700 million; the
cross-licensing of patents; supply of Intel and Alpha microprocessors;
and development of future systems based on Intel's 64-bit
microprocessors."
