2. The facts as stated in the plaint are that the plaintiff no.1 is a Corporation organized and existing under the laws of the United States of America with its corporate Headquarters at Masschusetts, in the United States of America.

The SOLIDWORKS software is a computer aided design software aimed at modeling and simulating three-
