IP Risk

IP Risk assesses the likelihood that a listing is facing or may face intellectual property enforcement by combining multiple signals — seller cliff events and review purge events. When both occur close together, the risk is significantly higher.

What It Measures

This is a composite metric that does not analyze raw data directly. Instead, it combines the outputs of the Seller Cliff and Review Purge algorithms to produce a risk assessment.

The key insight is that when sellers suddenly leave a listing (seller cliff) AND reviews are removed (review purge) around the same time (within about 4 weeks of each other), it strongly suggests a brand or rights holder is actively enforcing their intellectual property.

Why It Matters for Resellers

IP enforcement is one of the biggest risks for resellers:

• Brand owners can file complaints that result in listing removal, account warnings, or even account suspension.
• Gated listings may require brand authorization to sell, which many resellers cannot obtain.
• Legal action is possible in extreme cases, especially for trademarked or patented products.

Detecting these signals early lets you avoid investing in products that may become unsellable.

How We Calculate It

1. We check for seller cliff events (sudden drops in seller count).
2. We check for review purge events (Amazon removing reviews).
3. We look for concurrent events — a cliff and a purge occurring within 4 weeks of each other. This is the strongest signal.
4. We assign a risk level based on the combination:
   • Both signals concurrent = high risk
   • One strong signal (e.g., a large recent unrecovered cliff) = moderate risk
   • One weak signal (e.g., a small recovered cliff) = low risk
   • No signals = no risk

Large review purges (more than 50 reviews or more than 5% of total reviews) increase the risk assessment.

How to Read the Results

| Risk Level | What It Means | |------------|---------------| | None | No IP risk signals detected. The listing appears safe from enforcement activity. | | Low | Minor risk signals are present but may be coincidental. Keep an eye on the listing but no immediate concern. | | Moderate | Multiple warning signs suggest possible IP enforcement. Research the brand's history with third-party sellers before investing in inventory. | | High | Strong signals indicate likely IP enforcement activity. Seller exits and review removals suggest the brand is actively protecting this listing. Avoid unless you have brand authorization. |

Limitations & Caveats

• Requires both seller cliff and review purge data for a full assessment. If neither is available, the metric reports "insufficient data."
• Concurrent events are not proof of IP enforcement. Seller exits and review purges can coincide for unrelated reasons. The metric flags correlation, not causation.
• Some brands enforce intermittently. A listing may show low risk today but face enforcement next month if the brand changes its strategy.
• Authorized resellers are not affected. If you have a legitimate distribution agreement with the brand, IP enforcement should not impact you.
• New enforcement tools. Amazon regularly introduces new brand protection tools (Transparency, Brand Registry 2.0, etc.) that may create new enforcement patterns not captured by this metric.

Related Metrics

• Seller Cliff — One of the two input signals for IP risk. Sudden seller exits are often the first visible sign of enforcement.
• Review Purge — The other input signal. Review removals indicate Amazon is cleaning up the listing.
• Seller Concentration — After IP enforcement, the seller landscape often shifts dramatically.
