Cookie's Bustle?
Cookie's Bustle: Mysterious Bombo World is a 1999 Japanese point-and-click Adventure Game created by Keisuke Harigai and published by Rodik as their first and only release for Microsoft Windows and Apple Macintosh.

You play as Cookie Blair, a five-year-old who thinks she is a teddy bear. She has travelled to Dero City (run by.. aliens?) to take part in an international sports competition, in an attempt to win a gold medal!
TL;DR?
"Brandon White" registered a new trademark for Cookie's Bustle in 2021. This was followed by a trademark registration in the United Kingdom by "Keisuke Harigai" under a PO Box fowarding address for Cookie's Bustle.

In September, 2022, DMCA takedowns began being issued by a "Graceware, SL" of Andorra, a company with no presence anywhere.

In October, 2022, further DMCA takedowns were issued by UKIE, a UK-based trade-body for the gaming industry which offers IP and cybercrime services.

In December, 2022, Graceware applies for Cookie's Bustle trademarks, followed by further DMCA takedowns.

In February, 2023, further DMCA takedowns are issued, this time under "Web Capio", an anti-piracy company and member of UKIE. Some of these takedowns are issued under the company director's name, though this may not be relevent.

What's the deal?
During 2022 and continuing onto 2023, someone decided to issue DMCA takedowns on multiple instances across the web of Cookie's Bustle - playthrough footage, music complilations, download links - whilst download links are not surprising, what caught peoples attention was that footage of the game being played was being struck down on YouTube and Twitch, despite falling under fair-use. This prompted people to begin digging into why on earth the copyright for a game from 1999 was being defended so harshly.

One of the first channels to be struck was Classics Of Gaming, which had originally been uploaded in April of 2019.

Shortly afterwards, an Internet Archive entry for the gamerip was taken down, requested by "UKIE on behalf of Nintendo". Odd, as the game nor developers have no ties to Nintendo. What about UKIE? UKIE are a United Kingdom-based trade body for the games industry, which offer "IP and Cybercrime service". RODIK Inc were a Japanese company, and Cookie's Bustle was never released overseas. So what gives?

People begun digging to figure out what was going on, and discovered some very odd (and recent) developments for the copyright of this obscure Japan-only game.

The YouTuber Patbytes found evidence of Cookie's Bustle footage being removed ~September 2022, by a company "Graceware" (GRACEWARE, SL), registered in Andorra. The address listed did not lead to Graceware, but a separate tax prep company. (Note; there are other companies trading under the name Graceware, such as the tupperware company, however these are irrelivent).

In February, 2023, further DMCA takedowns/copyright strikes began being issues under "Web Capio", an "anti-piracy" service based in Essex, United Kingdom, and a member of UKIE. Some of these were issued under the company director's name, though this may just be a formality.

The Copyright Shinanigans
The original copywrite for Cookie's Bustle by Rodik ran out in 2008.

We can find that the copywrite for Cookie's Bustle was then registered to a Mr. Brandon White of Japan, for the brand and the games source code, registered in December of 2021, then a second copywrite for the gameplay concept was registered in 2022, again by a "Brandon White".

Another trademark for Cookie's Bustle was then filed in May of 2022 in the UK, under the name Keisuke Harigai.

In the United Kingdom, business and trademarks are registered either under a business name or a persons' legal name, which also displays the businesses address or home address of the applicant. Looking into Keisuke Harigai, we can see that the address is "354 Ripon House, Green Lane West, PRESTON, PR3 1XB, United Kingdom" - now don't worry, this isn't a dox, this address doesn't actually exist.

This address is tied to a mail forwarding company, MyUS (which may be connected to Forward2Me.com), where the number (354) is the "suite" number - essentially, this is just a PO Box for recieving mail from inside the UK, to be forwarded on elsewhere. Looking in a little further, you can find a number of non-UK companies whose registered address is "[Numbers] Ripon House, Green Lane West, [etc]".

This doesn't nessisarily mean the person is outside of the UK, as such businesses will also forward to addresses in the UK. PO Boxes are not uncommon, as they're useful for those who are privacy-concious - but in this case, we can safely assume this is being used to obfuscate the details of whoever is claiming Cookie's Bustle, whether they're in the UK, or Japan.

It's important to note the usage of the name Keisuke Harigai here, as he was the creator and writer of Cookie's Bustle. Whilst the game was developed in Tokyo, Japan at the time, it isn't impossible that Keisuke Harigai could have moved abroad to the United Kingdom, or Andorra, or... somewhere else.

There has been floated around the idea that the copywrite troll is some scorned collector, upset a rare part of their collection was leaked out for the world to see, but to go so far as to set up a shell company, and enlist multiple other companies in flagging down the copywrite is a bizarre step.
