body: "*The assignor has agreed to assign to the Company all of his intellectual property rights and title, interest in and to assigned rights relating to the business, technologies, software, products and services of the Company on the terms set out in this Deed.*"
  
  
  I have joined a startup and have been asked to sign a "Deed of assignment of intellectual property" document. My specific question is that does it mean whatever IP I owned till today automatically becomes their property? 
  
  
  There is another clause: "*To the extent that the Assignor owns (or if applicable owned) Intellectual Property Rights in the Assigned IP, the Assignor assigns to the Company (or if applicable confirms the assignment to the Company of) all of his or her right, title and interest in the Assigned IP.*" 
  
  
  I do not understand the legal stuff. I own a domain name and a patent. I also plan to own a company in a few years and am working towards it. Does it mean all that I develop in my personal time will belong to this company?
