Copyright and patent are two different things and are governed by two different Acts of law, i.e., (1) Copyrights Act, and (2) Patents & Trademarks Act.
While in certain cases copyright is acquired automatically on publishing, e.g. books, articles, specifications, even if not registered, but patent has compulsorily to be registered on invention or development of a prototype, if you want that none else should get any right to copy or manufacture in full or in parts or to make use of the name of the product. However, to avoid any dispute later with any third party, it is always better to register the copyright or patent in time. Copyright or patent, if not registered cannot be shown in the books of business, as an individual asset. Only the product can form part of the assets, not the patent/copyright.
