What protection can reach
Interior design copyright questions are less settled than most people expect. Drawings, renderings, and plans are generally protected as works of authorship, so copying them is often the clearest claim. The design of a building, including the arrangement of walls and interior spaces, can be protected as an architectural work, but standard features, functional elements, and decorative interior design such as furnishings and finishes generally fall outside that category. Individual furnishings are often treated as useful articles, protected only for artistic features that can be separated from their function. Paint colors, common layouts, and general styles are not protectable on their own.
Protecting your work from the start
Your client contracts often do more to protect you than copyright law alone. Agreements should say who owns the drawings and design documents, whether the client receives a license to use them for a single project, and what happens if the engagement ends before construction. Keep dated versions of concepts, renderings, and specifications. Registering key drawings or architectural works with the Copyright Office can matter if you need to sue, because registration generally must come first for US works and affects remedies. If you collaborate with architects or other designers, settle authorship between you in writing.
Reviewing a possible copying claim
We compare the protected elements of your work with what was copied, setting aside features any designer would use, and look at whether your contract already answers the question. Breach of contract claims are sometimes stronger than copyright claims in these disputes. If you are the one accused, we examine the same questions from the other side, including whether the similarities come from standard elements or a shared source. If you are accused, your own process records, such as sketches and sourcing notes, can show where your ideas came from. Bring the contract, your design documents with dates, and photographs or plans of the space in question.
