The applicant, Eva-Last Distributors, is the proprietor of sixteen registered designs (both aesthetic and functional) for an 'arched deck board' used in decking, cladding, and flooring products. The designs were applied for on 16 August 2016 and registered on 31 August 2016, with no release date initially recorded. The applicant sought an interdict against the first respondent (Timmdek) for alleged design infringement. The first respondent opposed, arguing the designs were not novel and formed part of the 'state of the art' due to prior disclosure by the applicant at a public exhibition (Decorex). Most infringement issues were settled. In response to the state-of-the-art challenge, the applicant applied to amend the design registration certificates to include a release date of 27 April 2016. The second respondent (Zentia Trading t/a Best Deck), which had joined the proceedings later, opposed the amendment application, contending the amendments were not clerical errors and that the designs were never registrable.
