IP Trend Analysis. Evidence Before the Decision.

IP trend analysis reads the direction of a technology field from its own paper trail – the multi-year record of patent filings, grants, litigation and licensing that every competitor leaves behind. A single year’s filing count tells you almost nothing; the slope across five or ten years tells you where R&D money is flowing, which jurisdictions are heating up, and whether a field is consolidating or fragmenting. This page explains what we measure, the signals that matter in the 2024-2025 data, and how strategy teams turn trend lines into decisions.

What IP Trend Analysis Actually Measures

IP trend analysis is not a single chart. It is the disciplined comparison of four data series over time, read together so the noise in any one of them cancels out:

• Filing volume – applications entering each office per year, the leading indicator of where R&D is being committed today.
• Grant volume and pendency – what actually issues, and how long it takes, which reveals office backlogs and examination pressure.
• Litigation and post-grant activity – district-court suits, inter partes reviews and reexaminations, the lagging indicator of where the money and the fights are.
• Assignee movement – which companies are climbing or retreating in a field, the human story behind the aggregate curve.

Because filings lead, grants lag and litigation lags further still, the three curves read in sequence give an early-to-late picture of a field’s whole life cycle – useful for timing an entry, a divestment, or a licensing push.

Signal 1 – The Global Filing Curve Is Still Climbing

The headline signal in the latest data is that patent activity is accelerating, not cooling. WIPO’s World Intellectual Property Indicators 2025 recorded roughly 3.7 million patent applications filed worldwide in 2024, up 4.9% on 2023 and a fifth consecutive year of growth – the fastest expansion since 2018. Filings have risen 3.4-fold over the past decade.

For a trend analyst the level matters less than the concentration: with Asia now taking just over 70% of the world’s filings and a single office accounting for nearly half, any field-level read has to be built on jurisdiction-aware data or it will simply mirror China’s national curve.

Signal 2 – Technology Fields Are Diverging Sharply

Aggregate growth hides the fields that are genuinely on fire. The EPO’s 2025 index shows digital communication applications up 11.4%, driven by the early 6G race, while semiconductor filings rose 7.6% overall – and grew more than 30% from some regions. A credible trend read segments to the technology-cluster level so a flat overall number does not mask a field doubling underneath it.

• Accelerating: digital communication / 6G, semiconductors, batteries, computing – the compute-and-connectivity stack.
• Reconfiguring: AI-adjacent fields, where filing spikes precede the litigation that has not yet arrived.
• Mature: fields where filings plateau while litigation rises – the classic late-life-cycle signature.

Signal 3 – Jurisdictional Shift Is the Strategic Story

The most actionable trend is where filings move, not just how many there are. Asia’s share of global filings has risen 10.1 percentage points in a decade. At the EPO, China entered the top three countries of origin for European patents for the first time in 2025, and Korea became the number-one semiconductor applicant in Europe. Each shift changes where you should be clearing freedom-to-operate, filing defensively, or watching for new entrants.

Signal 4 – Litigation and Post-Grant Trends Confirm the Field’s Maturity

Filings tell you where innovation is going; disputes tell you where it has already arrived and become worth fighting over. US data for 2025 shows patent case filings in district court up about 12% year over year, with NPE filings up 21.6% and high-tech matters now 58.9% of the docket. At the PTAB, 1,433 America Invents Act petitions were filed in FY2025 (95% inter partes review), and – as institution rates tightened – challengers pivoted hard to ex parte reexamination, which hit an all-time high, up 66% on 2024.

For a trend analyst these are late-cycle markers: a field with rising filings but low litigation is still open; a field with flat filings and surging disputes is crowded and defensive. Reading the two curves against each other is where the analysis earns its keep.

Signal 5 – From Trend Lines to Decisions

A trend series is only useful if it changes a decision. We deliver the analysis wired to the choices it should inform:

• R&D allocation – back the clusters whose filing slope is steepening before rivals crowd in.
• Licensing and monetization – time an outreach to the point where a field’s litigation curve turns up.
• Freedom-to-operate timing – clear jurisdictions before a filing shift makes them contested.
• M&A and diligence – price a target against the direction of its field, not just its current portfolio.

This is where trend work connects to our wider intelligence programme – it sets the direction that competitive landscape analysis, white-space mapping and freedom-to-operate studies then execute against.

How We Build the Trend Series

The quality of a trend read is decided before any chart is drawn – in how the data is assembled. We build each series from primary office records rather than a single commercial database, then normalise it so the curve reflects invention, not counting artefacts:

• Family-level counting. We count patent families, not raw publications, so one invention filed in eight offices is one data point – otherwise a globalising field looks like it is growing when only its filing footprint is.
• Assignee harmonisation. Corporate names fragment across subsidiaries, transliterations and acquisitions; we consolidate them so a company’s true trajectory is visible.
• Priority-date anchoring. We index each family to its earliest priority date, the moment the R&D decision was actually made, rather than the later publication date.
• Field definition. We fix the technology boundary with CPC/IPC classes plus a validated keyword layer, and hold it constant across every year so the trend is not an artefact of a shifting query.

Only once the series is clean do we overlay the litigation and licensing data. The discipline is unglamorous, but it is the difference between a trend you can bet a budget on and a chart that flatters a database’s coverage.

Common Pitfalls in Reading Patent Trends

Most misleading patent charts fail for one of a handful of predictable reasons. A trend read that ignores them will point a strategy in the wrong direction:

• The publication lag. Applications are typically published 18 months after filing, so the two most recent years always look artificially low. Reading the raw tail as a decline is the single most common error.
• Filing date versus priority date. Mixing the two shifts a whole curve by a year or more and can invert a genuine acceleration.
• Jurisdiction double-counting. Summing office-level counts without de-duplicating families inflates globalising fields and flatters offices with heavy foreign filing.
• Survivorship in litigation data. Only asserted patents litigate; treating the litigated subset as representative of a field’s whole portfolio overstates its risk.
• Policy shocks. Fee changes, examination-rule reforms and subsidy programmes create step-changes that look like organic trends until they are annotated against the calendar.
