@knightsforkcafe I’m not a lawyer (blah blah blah). It appears India has copyright laws. These laws apply to works created outside of India. The copyright need not be registered. Copyrights apply to “artistic works” and works of craftsmanship (wording used by India’s laws). This would apply to BCE.
izmet has various courses of action. He can issue cease and desist letters, he can report the copyright infringement to online retailers (like Etsy), report to payment processors and report to web hosting providers (I think this will be effective at getting the items delisted and cutting of funding for those items). Terms and services for those companies prohibit copyright infringement. Can be reported to government of India to block exports or for criminal prosecution. Or can be pursued civilly for damages (this is likely the most expensive option for the least gain).
in short, Chess Empire cannot legally infringe on copyrights. You are disputing wether copying BCE is copyright infringement.

The Copyright Act, 1957.
Act 14 of 1957, s. 14(c)
Copyright only applies to written works and not designs. Patents apply to designs. Like I said before it is crappy morally what The Chess Empire did but legally unless Slovenia and India have IP rights treaty between each other. The Chess Empire can legally do this. Now Izmet can ask for Slovenia Customs Enforcement to prevent The Chess Empire's version from being imported into Slovenia is about his only legal recourse.
