Executive Summary: The UK inventionINDEX
- The Core Metric: We evaluate regional innovation efficiency by benchmarking Granted Patent Growth against Regional GDP Growth.
- The Pivot Point: A ratio of 1% (1.00) acts as the neutral equilibrium (a ‘C’ Grade), adjusted for specific UK nations and regions.
- Performance Tiers:
- > 1.00%: Accelerated Innovation (Grades A / B / C+).
- < 1.00%: Innovation Deficit or Plateau (Grades C- / D / F).
The inventionINDEX provides a robust measure of the UK’s inventive output by juxtaposing economic expansion (GDP) with intellectual property generation. This document outlines our analytical framework, establishing a 1% (1pc) threshold as the standard baseline grade.
The index relies on a normalised formula to prevent regions with naturally larger economies (like Greater London) from inherently skewing as more innovative. The relationship is defined as follows:
| Variable | UK Data Source | Analytical Purpose |
|---|---|---|
| Patents | UKIPO (Intellectual Property Office) | Quantifies raw regional inventive success. |
| GDP | ONS (Office for National Statistics) | Provides regional economic scale for accurate data normalisation. |
By plotting historical inventionINDEX data, we apply a standard linear regression model to forecast expected regional performance baselines.
- Y (Forecasted Baseline): The anticipated index score.
- M (Slope/Gradient): The historical annual rate of fluctuation.
- x (Time): The specific year in the dataset.
- C (Y-Intercept): The initial starting point of our regional data trend.
Sample UK Regional Variations
The table below illustrates sample regression parameters applied to distinct UK regions:
| UK Region | Slope (M) | Intercept (C) | Notes |
|---|---|---|---|
| Greater London (LON) | 2.45 × 10-3 | -0.0150 | Standard regression model* |
| Scotland (SCO) | 8.12 × 10-5 | 0.0055 | Standard regression model* |
| North West (NW) | 6.33 × 10-5 | 0.0180 | Standard regression model* |
| West Midlands (WM) | 3.14 × 10-5 | -0.0110 | Standard regression model* |
We use the 1% median to dictate our baseline score. Regional scores are assigned an alphanumeric grade based on their deviation from this median.
| Grade Tier | Calibration | Economic Sentiment |
|---|---|---|
| A / B | Region Specific | Accelerated Growth: R&D and patent output outpace regional economic growth. |
| C | Region Specific | Equilibrium: Innovation advances in tandem with the broader economy. |
| D / F | Region Specific | Innovation Deficit: Intellectual property output is lagging, signalling potential future competitiveness risks. |
Every UK region is calibrated independently based on its own historical R&D and patenting trends. For instance, if the South East achieves a numerical score of 1.50%, it might receive a ‘B’ grade. However, that exact same 1.50% score in Northern Ireland—which has a historically different baseline—might yield an ‘A’ grade. The inventionINDEX ensures regions are judged against their own historical capabilities rather than solely against distinct geographic powerhouses.

While Swanson Reed champions the utility of the inventionINDEX to map economic vitality alongside R&D tax relief landscapes, we recognise the inherent limitations of standard regression models*. These constraints include tracking “hollow growth”, accounting for defensive IP strategies, and acknowledging unpatentable trade secrets that hold equivalent economic weight to formalised patents. A comprehensive review of these limitations can be found in our methodology review document.
Swanson Reed is an independent consultancy specialising in HMRC R&D tax relief claims. We do not generate direct financial gain from the inventionINDEX. Please note that legal fees associated with patent applications are generally not qualifying expenditures under standard HMRC R&D tax incentive schemes. The promotion of this index is purely educational, serving to inform policymakers, businesses, and the broader UK innovation ecosystem.
