There is a risk that your design, even if created independently, does not produce on the user a different overall impression to that of an earlier design.
Because of this it is important to conduct design searches to assess the risks of infringing some one else's rights.
We advise you on where and what to search, arrange for searches to be conducted and provide commercial and practical advice on the results of the search and on the extent to which you will be free to exploit the design.
