Philippine Republic when it declared war against the United Kingdom and the United States in 1944, by soldiers and civilians during the attempted coups d'états against President Corazon Aquino's administration, and by militants and rallyists during EDSA III. Subdivision insignia The usage of the Philippine flag as an element of a local government unit's (LGU; provinces, cities, and municipalities) seal is discouraged as per Memorandum Circular 92-30 of the Department of the Interior and Local Government. The usage of the flag is permissible if the flag itself has been part of the LGU's history such as in the case of Kawit, Cavite which is the site of the declaration of Philippine independence. In intellectual property The Philippine Flag itself is not eligible to be trademarked according to the Intellectual Property Office of the Philippines (IPOPHIL) since the flag is "owned by the public" in line with prohibitions on the flag's usage stated in Republic Act 8491. The Paris Convention for the Protection of Industrial Property, which the Philippines is a member of, also prohibits the registration of the state flags of its members as trademark. However both small and large businesses in the Philippines have used elements of the Philippine flag for their intellectual property. When it comes to this concern, the IPOPHIL has allowed businesses to use elements of the flag to invoke the national symbol as long as the intellectual property is neither a "true representation" of the Philippine flag nor a "modification that would amount to defacement of the flag". Prohibited acts According to Republic Act 8491 itself, it shall be prohibited: a) To mutilate, deface, defile, trample on or cast contempt or commit any act or omission casting dishonor or ridicule upon the flag or over its surface; b) To dip the flag to any person or object by way of compliment or salute; c) To use the flag: 1) As a drapery, festoon, tablecloth; 2) As covering for ceilings, walls, statues or other objects; 3) As a pennant in the hood, side, back and top of motor vehicles; 4) As a staff or whip; 5) For unveiling monuments or statues; and 6) As trademarks, or for industrial, commercial or agricultural labels or designs. d) To display the flag: 1) Under any painting or picture; 2) Horizontally face-up. It shall always be hoisted aloft and be allowed to fall freely; 3) Below any platform; or 4)
