Technosoft

Some staff members left Technosoft to start the game development companies Arsys Software in 1985 (founded by Kotori Yoshimura, creator of Thunder Force and Plazma Line), CAProduction in 1993, and Ganbarion in 1999.

In 2006, the URL for Technosoft was registered and updated. However, no updates other than "We will restart soon! Please wait for a while." and "THUNDERFORCE is a registered trademark." have been added to the website. In 2008, The Technosoft brand was revived by Twenty-One company. Technosoft licensed merchandising and music of the brand's past titles. The copyright for Technosoft's intellectual properties were not registered under Technosoft nor Twenty-One Company, but to Kazue Matsuoka.

Sega revealed that Thunder Force III will be part of Sega 3D Classics Collection, and on September 17, 2016, at the Tokyo Game Show, Sega announced that they acquired the intellectual property and development rights to all the games developed and published by Technosoft. When questioned about future Technosoft releases, Sega would look into re-releasing Thunder Force IV, Thunder Force V and Herzog Zwei.

In September 2016, there was a total of 21 registrations made by Sega Holdings. These registrations revised the copyright of Technosoft intellectual properties from Kazue Matsuoka to Sega Games Co, Ltd thus completing the acquisition. As of 2016, the digital soundtrack rights for the Thunder Force series will still be handled by Twenty-One Company through the Twenty-One Technosoft division.

Factors that influenced the acquisition included the former Technosoft president stating that they did not want the Technosoft brand to desist, and so handing over the intellectual properties to Sega was the only other option. Sega and Technosoft also had an established collaboration during the Genesis/Mega Drive era and so this pre-established relationship was also a factor when acquiring the brand rights to Technosoft titles.
