All government agencies such as the Intellectual Property Office of the Philippines (IPOPHL) are directed to promote the use of alternative dispute resolution (ADR) in resolving disputes and cases. This is mandated by the ADR Act of 2004. In the IPOPHL the rules concerning mediation procedure are provided in Office Order No 154. This took effect on October 5 2010. Since then, all cases filed with the adjudication bureau of the IPOPHL, the Bureau of Legal Affairs (BLA), such as oppositions, cancellations, and intellectual property violations, are referred to mediation, after the answer has been filed. Since 2010, the office of the Alternative Dispute Resolution Services under the BLA, has settled an average of 1/3 of said referred cases, which has greatly lightened the backlog of undecided cases at the BLA. Under 154, the referral to mediation is mandatory, but the mediation itself is voluntary.
