Acorn Computers Ltd v MCS Microcomputer Systems Pty Ltd

Acorn Computers Ltd commenced proceedings against MCS Microcomputer Systems Pty Ltd in the Federal Court of Australia, seeking relief related to the alleged infringement of copyright. The dispute centred on the validity of an assignment of copyright from Acorn to MCS, and whether MCS was entitled to use the copyrighted material in question. The court was required to determine whether the assignment was valid and whether the copyright in the material was assignable by one joint owner.

The primary legal issue before the court was whether the assignment of copyright from Acorn to MCS was valid. The court considered whether the assignment was in writing as required by section 196(3) of the Copyright Act 1968 (Cth), and whether the joint ownership of the copyright had characteristics of tenancy in common. The court also examined whether the assignment was made for value, and whether the equitable ownership of the copyright had arisen out of an agreement to assign.

The court held that the assignment was not in writing as required by section 196(3) of the Copyright Act, and that the equitable ownership of the copyright had arisen out of an agreement to assign. The court found that the joint ownership of the copyright had characteristics of tenancy in common, and that one joint owner was entitled to assign their share of the copyright without the consent of the other joint owner. However, the court held that the assignment was not valid because it was not in writing. The court also held that the applicants were entitled to amend their statement of claim to clarify the nature and extent of the copyright in the relevant works.

The court ordered that the applicants have leave to amend the statement of claim, and to deliver further particulars of each work in which copyright is claimed. The court also ordered that the respondents have liberty to apply should any question arise as to the sufficiency of the particulars delivered by the applicants, and that either party have liberty to apply generally. The court reserved costs.
