The legal notice claims that Mr. Roy's statement with regard to the ownership of the "Bishwa Bangla" logo and Jago Bangla newspaper were "false".
The Trinamool Youth Congress, which is headed by CM Mamata's nephew Abhishek Banerjee, is organising the show on Rani Rashmoni Road where the party wants the attendance to dwarf the BJP's Friday rally count.
The Home secretary said that Biswa Bangla is not only a corporation or a logo.
State's Additional Chief Secretary Rajiva Sinha had said: "The Biswa Bangla Marketing Corporation was incorporated in December 31, 2014 and its share holders are three government officials".
"She is the creator and we are the user of the logo".

Talk show host Stephen Colbert and actress Gal Gadot, the star of the blockbuster movie "Wonder Woman", also made the list. As the editors stated, Kaepernick doesn't say much in public these days.
Sinha said when the government had approached the registry of trade marks, the authorities had said that two other applications were also submitted for it.
"Any department of the state government can use it", he said. "I heard of that the legal notice would be served to me".
The State Government had immediately refuted the allegations regarding the Biswa Bangla stating that the company, brand and the logo "Biswa Bangla" is exclusively owned by the Government of West Bengal.
He also reiterated: "It is a government company and rights to the logo have been transferred to the company. Since the government has promoted the brand, someone must have gained financially", said Mukul Roy's advocate Som Mondal.
Meanwhile, taking a dig at Roy, suspended Trinamool MP Kunal Ghosh on Saturday alleged a Rs 9.18 crore was received by the Trinamool from different entities for elections and a majority of the fund came when Roy served the party as its General Secretary.
