Last week we reviewed how
lack of early patenting left the door open for Microsoft to grab Netscape's
bananas. Now let's look at a story where a much smaller chimp was able to
make the Gorilla pay for it. This story goes way back to when the MS-DOS
operating system was the dominant platform for PCs and hard disk drive storage
space was at a premium. Software developers were developing data compression
software to increase the effective size of the hard disk drive. The leader in
data compression for DOS operating systems was a small software company based in
Carlsbad, California, Stac Electronics (Stac). Although Microsoft dominated
everybody in its sales of the MS-DOS operating system primarily through its
sales to OEMs, it had not developed its own data compression technology for
MS-DOS. In contrast, the Novell DR-DOS operating system had it.
In 1991 Microsoft requested Stac
grant a world wide license of its data compression technology for its future
MS-DOS operating systems. According to Stac's complaint, Microsoft took the
position that it did not have to pay a royalty for the license. Microsoft
instead suggested that failure to reach an agreement just meant Microsoft would
go to another developer, which would have a definite impact on Stac's sales.
Negotiation broke off in June 1992. Shortly afterward, the industry became aware
that Microsoft intended to release the MS-DOS 6.0 operating system, including a
data compression utility called DoubleSpace, sometime in the first six months of
1993. Stac then resumed effort to reach an agreement in November 1992, but was
again unsuccessful. However, Microsoft agreed to send a beta copy in January
1993. When Microsoft released the beta copy it attempted to reassure Stac in
writing: "Don't worry about the patent stuff. We are just going to keep with our
changed code which does not infringe."
After review of the beta
copy, Stac somehow reached a different conclusion and sued Microsoft for patent
infringement, copyright infringement, and trade secret misappropriation. The
court ruled Microsoft had not infringed the copyright nor misappropriated any
trade secret, but had infringed the patent(s) and awarded Stac a permanent
injunction against future patent infringement and $120M in damages. After about
a week of shipping the MS-DOS operating system without the data compression,
Microsoft negotiated a settlement reportedly worth $83M to Stac for the right to
license, for a royalty, any of Stac's existing or future technology including
that unrelated to data compression and Stac received a license to some of
Microsoft's technology.
The decision was not
precedential, but is worth remembering.
