Lewis H. Titterton Jr. shows a genuinely active buying pattern across two companies, in contrast to the compensation-driven profiles common in this dataset. At Anixa Biosciences (formerly ITUS Corp), 174 transactions since 2011 show 5,553,320 shares bought against 6,829,442 sold — but critically, many of the buys are real open-market purchases, not grants: a cluster in January 2025 (1,000 to 10,000 shares at a time, priced between $2.57 and $3.01) and continued purchases through 2026, most recently 2,836 shares at $2.64 on June 16, 2026 and 2,797 shares at $3.28 on July 15, 2026 — his latest recorded transaction. At ParkerVision, 20 transactions since 2018 show 4,761,905 shares bought and zero sold — dominated by a single large purchase on November 18, 2025 of exactly 4,761,905 shares at $0.21, which works out to almost precisely $1,000,000. A large 2,000,000-share gift transaction on January 6, 2025 and two 1,699,844-share note-conversion transactions on May 6, 2025 round out his ParkerVision activity.
