2.2 Deciding Whether and How to Enforce a Patent

Patent Enforcement Strategies

When you hold a patent, you have the legal right to exclude others from making, using, or selling your invention. But a patent doesn't enforce itself. You need to decide whether enforcement is worth pursuing and, if so, how to go about it. That decision depends on your business goals, your budget, and the nature of the infringement.

Options for Patent Enforcement

There are several paths a patent holder can take, ranging from cooperative arrangements to aggressive legal action.

Licensing

Licensing grants another party the right to use your patented invention, usually in exchange for royalty payments. There are a few flavors:

• Exclusive license gives one licensee the sole right to use the patent. Polaroid used this approach with its instant camera technology, keeping tight control over who could practice the invention.
• Non-exclusive license allows multiple licensees to use the patent simultaneously. The MP3 audio coding format was licensed this way, enabling widespread adoption across many manufacturers.
• Cross-licensing is when two or more parties license patents to each other. Microsoft and Samsung, for example, entered a cross-licensing deal covering smartphone patents, which let both companies avoid costly litigation.

Selling the Patent

Selling transfers ownership entirely. The buyer gets all rights, and the original holder walks away with a lump sum. Kodak, for instance, sold a portfolio of digital imaging patents to a consortium of tech companies when it needed to raise capital during bankruptcy.

Litigation

Filing a patent infringement lawsuit in federal court is the most direct enforcement tool. Apple v. Samsung is a well-known example of patent litigation in the smartphone space. Through litigation, a patent holder can seek:

• An injunction to stop the infringer from continuing to make, use, or sell the patented invention
• Monetary damages for past infringement, calculated as either reasonable royalties or lost profits

Alternative Dispute Resolution (ADR)

ADR offers ways to resolve disputes outside of court, which can be faster and less expensive:

• Mediation uses a neutral third party to help both sides reach a voluntary settlement. The WIPO Mediation and Arbitration Center handles these kinds of disputes internationally.
• Arbitration is a private process where a neutral arbitrator makes a binding decision. The International Chamber of Commerce is one organization that administers patent arbitrations.

ITC Proceedings

The International Trade Commission can investigate unfair practices in import trade under Section 337. If infringing products are being imported into the US, the ITC can issue exclusion orders barring those products at the border. Segway used this route when it filed a complaint against companies importing infringing hoverboards.

Patent Assertion Entities (PAEs)

Also called non-practicing entities (NPEs), these are companies that acquire patents not to manufacture products but to enforce them against others for licensing fees or settlements. Intellectual Ventures is one of the most prominent examples. Whether you view PAEs as legitimate enforcers or problematic "patent trolls" depends on your perspective, but they're a real part of the enforcement landscape.

Costs and Rewards of Enforcement

Deciding to enforce a patent is a cost-benefit analysis. Here's what goes into that calculation.

Time Considerations

Patent litigation is notoriously slow. A typical case moves through several stages:

1. Discovery phase: both sides exchange information and evidence, which can take months or even years in complex cases
2. Trial phase: arguments and evidence are presented before a judge or jury
3. Appeals: the losing party can challenge the outcome, adding more time

Meanwhile, the clock is ticking. Patents last 20 years from the filing date, so the remaining patent term directly affects how much enforcement is worth. If your product has a short market window, delays in enforcement can erode the value of winning.

Cost Considerations

• Legal fees for patent attorneys and technical experts are substantial. Full patent litigation in the US can cost millions of dollars.
• Court costs and filing fees add to the financial burden.
• Opportunity costs matter too. Time and attention spent on litigation is time not spent running your business.

Potential Rewards

• Monetary damages: courts can award reasonable royalties (based on what a hypothetical licensing deal would have looked like) or lost profits (the money you would have made without the infringement).
• Injunctions that stop the infringing activity and prevent further losses.
• Licensing revenue from deals negotiated as part of a settlement or post-litigation.
• Market position: eliminating an infringer can restore your competitive advantage and increase market share.
• Deterrence: successful enforcement sends a signal to others that you will protect your patents.

Strategic Planning for Enforcement

Enforcement works best when it's planned, not reactive. Here's how to approach it:

1. Identify Your Objectives

What are you actually trying to achieve? Common goals include:

• Protecting market share against competitors
• Generating licensing revenue as a return on R&D investment
• Preserving exclusivity in a key market
• Building a reputation as a company that defends its IP (which deters future infringers)

2. Assess Your Resources

Be realistic about what you can commit:

• Financial resources determine how aggressive you can be. Full litigation is expensive; licensing negotiations or ADR cost less.
• Human resources for managing the process matter. Someone needs to oversee enforcement efforts.
• Patent portfolio strength affects your position. A broad, well-drafted portfolio is easier to defend and harder for opponents to design around.

3. Prioritize Targets

Not every infringer is worth pursuing. Focus on:

• Key competitors or markets where infringement poses the greatest threat to your business
• High-value infringers whose products closely match your patented invention

4. Choose Your Method

Match your enforcement approach to your objectives and resources. Sometimes aggressive litigation makes sense; other times, a cooperative licensing approach preserves business relationships while still generating revenue.

5. Set a Timeline and Budget

• Allocate resources over the expected duration of enforcement
• Monitor results and adjust your plan as circumstances change

6. Consider Reputational Impact

Enforcement actions are often public. Overly aggressive tactics can generate backlash, especially if they're perceived as anti-competitive or as stifling innovation. Communicating your reasoning to stakeholders helps maintain transparency.

Patent Management and Strategy

Enforcement decisions don't happen in a vacuum. They're part of a broader patent strategy:

• Patent portfolio management means strategically building and maintaining a collection of patents that support your business objectives, not just filing patents for the sake of it.
• Patent valuation assesses the economic worth of your patents, which informs whether to enforce, license, or sell them.
• Patent strategy aligns your IP protection with your overall business goals, factoring in market position and the competitive landscape.
• Patent due diligence is the thorough investigation of patent assets, typically done before transactions (like acquisitions) or before launching enforcement actions.
• Patent prosecution refers to the process of actually obtaining patent protection: drafting applications, responding to patent office rejections, and negotiating claims. Strong prosecution lays the groundwork for strong enforcement later.
