When a world record moves a share price: IP in sportswear

On 26 April 2026, the London Marathon delivered moments with implications well beyond athletics. World records were broken in both men's and women-only races. In the case of the men's race, the winner crossed the finish line in under two hours, the first time the barrier had been broken in a competitive marathon setting.^[1] The global reaction was immediate^[2]. The conversation shifted from the athlete's performance to the technology on his feet; a shoe weighing less than 100 grams, engineered through three years of materials science research, and priced at five times the cost of a standard running shoe.

When a shoe, protected by a portfolio of patents and registered designs, can be credited with contributing to a world record, it becomes more than a product. It becomes a demonstration of the brand's capability, a signal to investors, and a competitive threat to rivals.

This article discusses how the intellectual property behind elite sports footwear protects both the immediate market reaction to a breakthrough and the long-term value of the brand behind it.

It looks at:

• Brand value as a long-term asset
• How innovation creates value overnight
• The halo effect: When one record sells the whole brand
• How brands make an innovation hard to copy
  • Layering different types of intellectual property protections over each other
  • Timing your application
  • Review regulatory considerations
• What comes next
