The main legal point established in the judgment is that in a claim of copyright infringement, the plaintiff must provide substantial evidence of substantial copying or infringement of the copyrighted work. The court also emphasized the importance of timely legal action and the need for material evidence to support the claim of infringement.

( 1 ) THE plaintiffs in O. L. C. S. No. 1 of 1958 on the file Of the District court at Dharwar are the appellants in this appeal. They are a firm of partners called Janata Pictures, doing business at Dharwar of exhibitors and distributors of cinematograph films. Under a document marked Ex. 57 in the case dated 24th October 1953, they secured the rights of exhibition distribution and exploitation of a Hindi talkie film called Nagapanchami in the territory called the Karnatak territory comprising the districts of Belgaum, Dharwar, Bijapur and North Kanara. The producer of the said film is the 4th defendant, Vinod Films, of which the sole proprietor is Vinod C. Desai. He had assigned to the 3rd defendant Chandra Film distributors, whose proprietor is a brother of his by name C. C. Desai, the distribution rights in Respect of what is called the Bombay Circuit , which includes the Karnatak area mentioned above. They commenced screening the film shortly thereafter and continued to do so till about January 1956.

( 2 ) ON or about the 13th of January 1956, the 2nd defendant, Srinivas pictures, started exhibiting a Kannada talkie film called Adarsha Sati at dharwar, produced by the 1st defendant A. V. M. Productions and the distribution rights of which are said to belong to defendant 1-A, a private limited company called the A. V. M. Ltd. The plaintiffs stated that they wrote a letter (original of Ext. 60) dated 6th February 1956 to the 1st defendant with a copy to the 4th defendant, but received no reply. On 30th july, 1956, they wrote a post registered letter, Ex. 61, repeating their complaint in the previous letter that the exhibition of the Kannada talkie film adarsha Sati is an infringement of their rights in respect of 'nagapanchami. The 1st defendant in his reply Ex. 62 dated 2nd August 1956 repudiated the claim. On 17th August 1957 they issued a notice through ' a lawyer to the 1st defendant (Ex. 63), to which no reply was received. The suit was filed on 4th June 1958 in which they complained that the exhibition of the Kannada talkie film Adarsha Sati constituted an infringement of their rights in respect of the Hindi talkie film Nagapancami acquired under Ex. 57 and prayed for a decree granting an injunction restraining the defendants from exhibiting the said Kannada film Adarsha sati, together with incidental reliefs like surrendering the prints, rendering an account, etc.

( 3 ) BESIDES raising minor pleas, such as the plaintiffs' firm is not registered under the Partnership Act, and one of the partners as Manager of a picture house in Dharwar has himself been responsible for the exhibition at the said Picture House of the offending film Adarsha Sati, both of which are decided against the defendants and are not repeated before us the principal defence of Defendants 1, 1-A and 2 was that there was no infringement at all of any rights of the plaintiffs. Defendants 3 and 4 have remained ex parte both in the trial Court and in this appeal also. The 4th defendant Vinod C. Desai, however, as the only witness for the defendants examined on commission has deposed that under a deed of assignment, Ex. 123 dated 23rd June 1964, he has assigned to the 1st defendant his entire copyright in respect of the Hindi film Nagapanchami, limited to its Tamil, Telugu and Kannada film versions.

( 4 ) THE trial Court has upheld the defendants' plea that no rights of the plaintiffs in respect of the Hindi talkie film Nagapanchami have been infringed by the defendants exhibiting in Karnatak area the Kannada talkie film called Adarsha Sati and dismissed the suit. Hence this appeal.

( 5 ) IN the plaint the plaintiffs have also alleged that a Telugu film called nagalu Chouti similarly constituted an infringement of their rights; but the apprehension on the likelihood of its being exhibited in Karnatak area stated in the plaint has not materialised, nor is there any evidence of the same having been so exhibited. We shall not therefore mak
