Are digital signatures valid for Australian intellectual property assignments?

Yes, digital signatures are legally valid for Australian intellectual property assignments under the Electronic Transactions Act 1999 (Cth). This legislation recognizes electronic signatures as equivalent to traditional wet-ink signatures, provided they reliably identify the signer and indicate their intention to sign. IP Australia, the authority overseeing patents, trademarks, and designs, accepts digitally signed assignments as long as they meet these reliability criteria.
