An individual X was employed by a software company A, where he was designing proprietary algorithms
and developing software for "business process optimization". His employment started in 1998, and in
2002 he was laid-off as company was downsizing and decided stop developing the product.
There are no known patent applications filed to protect any rights related to the product design.
In 2003 X started independent development of the software product with similar functionality and
characteristics based on a different algorithm written in a different programming language and under
a different name. First version of the product was available in 2004.
In 2010 company B acquired company A assuming all rights, and soon after development of the original
product was resumed. There are reasons to believe that company B would make an effort to stop X from
developing and marketing a "competing" product and is researching legal options.
What X should be worrying about?
Best Regards
