Mr. Suman
As per your query we gathered that
1. you are just authorising another Company to use the Trade mark under permitted purpose for specific period
2. but you are retaining the ownership of the trade mark. after compleation of the period they have to reconvey the said to your company
In such circumstances you may go for Trade Mrak licensing agreement. Licensing is a one of the channels for authorized use of another’s trade mark such rights, which is granted by the owner of theTrademark to the authorized user,
