In Inform Design and Construction Pty Ltd v
Boutique Homes Melbourne Pty Ltd [2008] FCA 912  the Federal Court rejected a copyright claim in house plans (see previous note on Barrett v Metricon).

Kim Weatherall analyses the case in detail here: she concludes the defendant was able to substantiate its claim of independent design by producing a credible chain of evidence including a history of draft plans which evolved into the design in dispute which was similar to the plaintiff’s.
