Patent Thicket is a dense web of overlapping Patent rights that a company, or a group of companies, creates around a specific technology. Imagine trying to walk through a dense, thorny thicket where every branch is owned by someone different. Instead of one big patent for a smartphone, a company might file hundreds or even thousands of patents covering everything from the shape of the corners to a swipe-to-unlock gesture and the way data is processed. This dense jungle of Intellectual Property (IP) can be so complex and tangled that it becomes nearly impossible for competitors to develop their own products without infringing on at least one of these patents. While it can be a powerful defensive tool, it can also be used offensively to block rivals, demand hefty licensing fees, and ultimately stifle innovation across an entire industry.

How a Patent Thicket Works

At its core, a patent thicket is a strategy of quantity over individual quality. A company floods the patent office with applications for incremental, often minor, improvements on a technology. This creates a minefield for any potential competitor. If a rival company wants to launch a similar product, they must first navigate this dense thicket. The process involves either painstakingly designing around every single patent (which can be impossible) or paying for licenses to use the patented technology. This leads to a few common outcomes:

The Investor's Perspective

For a Value Investing practitioner, a patent thicket is a classic double-edged sword. It can be a sign of a strong, well-defended business or a red flag for costly legal battles and future stagnation.

The Good - A Formidable Competitive Moat

A robust and well-managed patent thicket can be one of the most powerful forms of a Competitive Moat. It creates high barriers to entry, protecting a company’s market share and profitability from would-be competitors. For example, a company like Qualcomm historically built an incredibly powerful business model based on its massive portfolio of patents essential to mobile communications. Any company wanting to build a 3G, 4G, or 5G phone had to pay Qualcomm a licensing fee. For an investor, this translates into a predictable, high-margin revenue stream, a hallmark of a high-quality business. When a company’s patents are truly fundamental to an industry and are actively defended, it can secure a dominant position for years, or even decades.

The Bad - Litigation Nightmares and Innovation Killers

On the flip side, patent thickets can be a massive drain on a company's resources and a sign of deeper problems.
