The question
We are an Environmental Engineering/Consulting firm that has developed a software, which we provide our clients. We have since renamed the product and spun off it's own website/entity - although we have not legally separated it from the consulting firm. Rather, it just has it's own name and website separate from the consulting firm. Do we legally need to setup a "doing business as" name, need to trademark the software "company" name, or will simply stating that "[Software] is a product of [Environmental Consulting Firm]" in all legal documents, ToS, etc.? Note: This software is sold to and used by companies all over the US. Some of our clients do use the software at facilities in other countries as well.
