The commissioner of Internal Revenue asks us to reverse a decision of the Tax Court holding that a debt owing to the petitioners’ decedent by the Pullenlite Company which became worthless in 1947 was deductible by the petitioners, in computing their decedent’s income tax liability for that year,- as a debt incurred in the decedent’s trade or business under Section 23 (k) (1) of the Internal Revenue Code. 26U.S.C. § 23(k) (1). The question whether the activities of a taxpayer constitute carrying on a trade or business is largely one of fact the solution of which “requires an examination of the facts in each case”. Higgins v. Commissioner, 1941,
It is true that the activities of an individual in investing and reinvesting his assets in corporate securities do not constitute a trade or business within the meaning of the Internal Revenue Code. Higgins v. Commissioner, 1941,
In the present case, however, the decedent was engaged in much more than merely investing his assets or merely managing corporations in which he was interested. He was, as the Tax Court found, “engaged individually in the business of exploiting patents”. It is true that he exploited his patents through corporations in which he was active. But the evidence established that his activities in locating, developing^ and exploiting patents involved much more than the mere investment of funds in and management of corporations. It was quite clearly a personal activity in which a major portion of the decedent’s lifetime thought and energy was enlisted

and in which he engaged continuously and regularly throughout his business career. In these respects this case differs from those relied on by the Commissioner and resembles Maloney v. Spencer, 9 Cir., 1949,
The decision of the Tax Court will be affirmed.
