Patent Portfolio Audit
You have a patent portfolio that has grown over years, and you need to know which rights are alive, which are approaching renewal or expiry, which applications remain commercially worth prosecuting, and where the current business is no longer adequately protected. Intepat maps both the maintenance cost and the strategic cost of gaps, covering Indian patent assets directly and foreign assets through its associate network on request. The output gives management and in-house counsel a clear basis for renewal, abandonment, and filing decisions.
Commission a portfolio auditWhat a patent portfolio audit answers
The audit addresses four practical questions:
What rights are alive?
The review confirms the live status of each granted patent and pending application against the official records in each jurisdiction in scope. For Indian assets, status is verified against IP India records. For foreign assets, verification uses official patent registers and, where required, the associate network. Rights believed to be active sometimes prove lapsed through missed annuities; the audit flags those discrepancies before they become irrecoverable.
What are the expiry and renewal windows?
The audit maps annuity due dates and final expiry dates for each active right. For Indian patents, term runs from the date of filing under the Patents Act, 1970; a lapsed patent may be eligible for restoration under Section 60, though restoration is not automatic and is subject to statutory requirements and time limits. Portfolios without centralised docketing frequently discover clustered renewal deadlines, creating cash-flow pressure that advance notice prevents.
Where are the coverage gaps?
The verified portfolio is mapped against the client's current products, processes, technology areas, and commercial geographies. This identifies three issues: patents that no longer support the business, active products without meaningful claim coverage, and pending applications whose present claim scope may not protect the relevant product even if granted.
Which applications are worth prosecuting?
The audit assesses prosecution status, examiner correspondence, and likelihood of grant in the current claim form. Applications with narrowed scope that no longer cover commercially relevant territory are candidates for abandonment or claim revision.
The audit can be scoped at different levels: a status and annuity check; a coverage analysis mapping claims against current products; or a strategic review adding prosecution prioritisation and gap-filling recommendations.
When to commission a patent portfolio audit
Before annual renewal payment.
Companies routinely pay annuities on portfolios not reviewed in years. An audit before the renewal cycle allows deliberate abandonment decisions rather than payment by default.
Before a fundraising round or investor due diligence.
Investors examine the portfolio regardless. An audit beforehand identifies vulnerabilities before they become negotiating points; the report can be shared under NDA as part of the data-room package.
When the product range has changed significantly.
R&D pivots, product exits, and market changes create gaps and surplus in a portfolio simultaneously.
Before enforcement decisions.
Status verification is a prerequisite for any infringement action or cease-and-desist letter. A patent not fully in force exposes the client to procedural and cost consequences.
When an acquisition or divestiture is under consideration.
Accurate status and gap-analysis information supports IP valuation before the transaction closes. This is distinct from Patent Due Diligence, which adds validity, freedom-to-operate, and encumbrance review.
Methodology
The audit is conducted in four stages.
Stage 1: Portfolio data collection.
The client supplies a working list of patents and applications by application number, jurisdiction, filing date, and patent family. Where the client does not hold a consolidated list, Intepat assists in constructing one from official patent registers and the client's docketing system. For Indian assets, Registered Indian Patent Agents retrieve live status records directly from IP India.
Stage 2: Status verification.
Each item is verified against the official patent office records for its jurisdiction. For Indian assets, this covers grant or refusal status, annuity position and due dates calculated from the date of filing, outstanding examination correspondence, and any registered encumbrances, assignments, or licences. Discrepancies are flagged individually.
Stage 3: Coverage analysis.
The verified portfolio is mapped against the business's current product and technology scope, which the client provides in a product brief. The analysis identifies: patents protecting products no longer in the client's market; products or processes not covered by any active claim; and pending applications whose claim scope, as currently framed, would not cover the corresponding product even if granted.
Stage 4: Opinion and recommendations.
Patent Agents with relevant technology backgrounds review the findings and produce a written opinion covering renewal-versus-abandonment recommendations, a priority list of gap-filling opportunities, and a docketing schedule for the next renewal cycle. Recommendations are graded by commercial relevance and cost impact.
What you receive
A status table for each patent and application, with confirmed grant or pending status, annuity position, next due dates, and final expiry dates.
A gap analysis section comparing the portfolio to the client's active product lines and technology scope.
Renewal-versus-abandonment recommendations for each active item, with the commercial rationale stated.
A priority list of filing opportunities arising from the gap analysis.
A forward annuity docketing schedule for the next 12 to 24 month renewal window.
Methodology limits
The coverage review identifies apparent alignment or mismatch between the claims and the client's current products and technology. It is not a formal infringement, claim-construction, validity, or freedom-to-operate opinion.
The audit does not assess the validity of granted patents or produce freedom-to-operate or infringement opinions. Validity requires a prior-art search and a written opinion on whether the patent would survive a revocation challenge under Section 64 of the Patents Act, 1970; that analysis is part of Patent Due Diligence or a standalone invalidity search.
The jurisdictional scope is confirmed before work begins. The audit may cover Indian assets only, or extend to a multi-jurisdictional portfolio.
Who this is for
How Intepat delivers
Patent portfolio audits covering Indian assets are conducted by Registered Indian Patent Agents with experience in patent drafting, prosecution, renewal review, and claim-scope analysis. The review is allocated to agents with relevant technology backgrounds so the coverage analysis reflects an accurate understanding of the claims and prosecution history. For portfolios that include foreign assets, jurisdiction-specific verification is coordinated through the foreign associate network.
Unlike a simple docketing review, Intepat's audit combines official status verification with claim-scope and business-coverage analysis, allowing the report to support both cost decisions and protection strategy. Recommendations are checked for internal consistency: an abandonment recommendation is cross-checked against the coverage map to confirm no unintended gap results.
Initial scoping requires only application numbers, jurisdictions, and a high-level product description. All instructions and materials are treated as confidential; conflict checks are run before any engagement opens.

Patent Portfolio Audit FAQs
What does a patent portfolio audit cover?
Four areas: status verification of each patent and application against the relevant patent office records; annuity position and forward due-date mapping; coverage analysis against the current product and technology scope; and renewal-versus-abandonment recommendations with a gap-filing priority list. The output is a structured written report with a forward docketing schedule. The audit does not cover validity, freedom to operate, or infringement.
When is a patent portfolio audit typically commissioned?
The most common triggers are the annual renewal cycle (to make deliberate abandonment decisions before fees are paid), a material change in the product range, preparation for investor due diligence or an M&A process, and a change of in-house IP leadership requiring a baseline. Audits are also commissioned after a period of minimal IP activity, where the portfolio has accumulated unreviewed items.
What is the deliverable structure?
A written report comprising a status table for each item in the portfolio, a coverage map against the current business, renewal-versus-abandonment recommendations with stated rationale, a gap-filing priority list, and a renewal docketing schedule covering the next 12 to 24 months. The report is prepared under standard confidentiality terms and structured for use in internal management discussions and investor data-room packages.
What criteria determine a renewal-versus-abandonment recommendation?
The primary criteria are commercial relevance and cost position. A patent protecting an active product in a market where the client competes should ordinarily be renewed; one protecting a product no longer in the client's range, or in a jurisdiction where the client has no commercial presence, is a candidate for abandonment. Secondary considerations include remaining term, the likelihood of third parties relying on the absence of the patent to enter the market, and whether the patent is cross-licensed or encumbered.
What is the relationship between a portfolio audit and patent due diligence?
A portfolio audit is a status and coverage review at the portfolio level, typically for internal strategic purposes. Patent due diligence addresses the additional questions specific to an acquisition or investment: independent validity assessment against prior art, freedom-to-operate of the target's products, encumbrance review, and confirmation that assignments have been properly recorded at the Patent Office. Due diligence uses the same status verification as a portfolio audit but adds those transactional layers.
How is the cost structured?
Audit fees depend on the number of items in scope, the complexity of the technology, and the level of coverage analysis required. A brief covering status verification and annuity mapping alone is costed differently from one that includes a coverage analysis against a detailed product list and a gap-filing opinion. Intepat provides an estimate after reviewing the portfolio list and confirming scope.
