Write short notes on the following: Patent Assignment.

Patent is a right, granted by the Government under the Patents Act, 1970 (Act) to the grantee, of exclusive privileges of making or selling a new invention or process protected under the patent. The Act confers upon the patentee the right to safeguard his property in the patent and sue the person who infringes upon his patent right. After a complete specification in pursuance of an application for a patent has been accepted and on the request of the applicant, the Controller shall cause the patent to be sealed with the seal of the Patent Office under Section 43 of the Patents Act, 1970. Section 48 of the Act, confers upon the Patentee where the subject matter of the patent is a product, the exclusive right to prevent third parties who do not have his consent from the act of making, using, offering for sale, selling or importing for hose purposes that product in India. Where the subject matter of the patent is a process, the patentee is given exclusive right to prevent third parties who do not have his consent from the act of using that process and from the act of using, offering for sale, selling or importing for those purposes the product obtained directly by that process in India provided that the product obtained is not a product in respect of which no patent shall be granted under this Act. Section 68 of the Act makes provision with regard to the assignment of patents. The Section lays down: "An assignment of a patent or of a share in a patent, a mortgage, licence or the creation of any other interest in a patent shall not be valid unless the same were in writing and the agreement between the parties concerned is reduced to the form of a document embodying all the terms and conditions governing their rights and obligations and duly executed." Section 69 of the Act provides the provisions for Registration of assignments, transmissions, etc. Section 69(1) prescribes that where any person becomes entitled by assignment, transmission or operation of law to a patent or to a share in a patent or becomes entitled as a mortgagee, licensee or otherwise to any other interest in a patent, he shall apply in writing in the prescribed manner to the Controller for the registration of his title or, as the case may be, of notice of his interest in the register. Section 70 of the Act provides the provisions relating to Power of registered grantee or proprietor to deal with patent. It states: "Subject to the provisions contained in this Act relating to co-ownership of patents and subject also to any rights vested in any other person of which notice is entered in the register, the person or persons registered as grantee or proprietor of a patent shall have power to assign, grant licences under, or otherwise deal with, the patent and to give effectual receipts for any consideration for any such assignment, licence or dealing: Provided that any equities in the patent may be enforced in like manner as in respect of any other movable property."
