Philippine Nut Industry, Inc. v. Standard Brands, Inc.,
[GR L-23035. July 31, 1975]

“The non-use of a trademark or an article of merchandise due to legal restrictions or circumstances beyond one's control is not to be considered as an abandonment. Said rule was correctly applied to the case at bar where the use of the trademark was interrupted during the Japanese occupation and in fact was discontinued when the importation of the product covered by the trademark was prohibited by the Central Bank Regulations.”
