A spokeswoman for the family said they were receiving 3,000 emails a day with some suggesting how they could use Sir Tom’s name to raise money.
“There have been a lot of requests to Sir Tom’s family to create products with Sir Tom’s name on it claiming some of the proceeds would go to charity,” she said.
“However, the family cannot vet all these emails, so they wanted to make sure Sir Tom’s name or face only appears on those products or items he would be happy with.
“They sought some expert advice and were advised to get a blanket trademark application in an attempt to protect him.”
The couple made an application to trademark ‘Captain Tom’, ‘Captain Tom Moore, and ‘Captain Sir Tom Moore’ for items including books, DVDs, calendars, mugs, coasters, footwear, clothing and hats.
They are also applying to have those names protected for charitable fundraising activities and sponsorship.
Sir Tom was knighted after a special nomination by Boris Johnson, the Prime Minister, who said he had provided Britain with “a beacon of light through the fog of coronavirus”.
He had initially set out to raise £1,000 for NHS charities by walking laps of the 82ft loop in his garden. However, he raised more than £32 million.
The need for a trademark application became even more urgent after he set up a charitable foundation which he aims to use to combat loneliness, help the bereaved and support hospices.
