The Empty Space Is Not The Opportunity

A patent ranking looks like research. It is arithmetic, and the arithmetic is the point. Five columns carry the whole model: patentability, business value, technical feasibility, enforceability and freedom to operate. Each scores out of 100. The composite is a plain average with equal weights, and the equal weighting is deliberate. The moment one column takes a coefficient, the score stops being a reading of an opportunity and starts being a preference for whoever chose the weighting. The bands come with the model. Eighty and above, file now. Seventy to seventy-nine, file with care. Sixty to sixty-nine, re-scope. Below sixty, shelve it and stop paying attention to it. But the number at the end is the least interesting thing on the sheet. The information is in the spread. An entry can carry 95 for patentability and 65 for feasibility and land on 84, and the twenty points between those two columns are the entire project plan. A second entry can carry 90 for business value and 50 for enforceability and still land at 66, and the fifty points between those two are the reason it should not be drafted at all. Five columns, one hundred points, and one rule that costs nothing to write down and a great deal to ignore. Nothing is filed until every column is a number somebody can defend with a document. That is the whole method.

Run the model against the public record of small-drone warfare and the top of the sheet is not a drone at all. It is the wire. Fibre-optic tether control, where a spool of glass fibre pays out behind a first-person-view airframe and the control signal travels down a physical line instead of through the air, scores 92 out of 100. Patentability 95. Business value 95. Freedom to operate 95. Feasibility 85. Enforceability 90. Why every column leans the same way is unromantic. Commercial fibre spools in the 3 to 30 kilometre class are catalogue items. The problem they answer is the first failure mode of cheap drones, which is radio jamming. A drone on a wire has no radio link to lose and no emissions to find. The public record of combat use runs from August 2024 onward. And because the thing is physical, a spool, a payout mechanism, a brake, a cartridge, infringement can be seen by buying one and taking it apart. Nothing about the top score is exotic. It is a tether, a cartridge and a drag brake. The score is high because all five questions have an answer that can be checked rather than asserted, and because the filing does not depend on convincing anyone that the physics works. It already works.

Here is the part that unsettles a tidy plan. The counter-measure to the highest-scoring idea scores almost as well. Detecting a fibre-optically guided drone means finding a tether under one millimetre thick that emits nothing, reflects almost nothing, and looks like nothing. That scores 84. Patentability 95, because no method has been claimed for it. Freedom to operate 100, because the field does not exist. Business value 85. Enforceability 90. Feasibility 65. That one column carries the whole difference between the two ideas. The published approaches are a structured light curtain, laser vibrometry on the tether itself, acoustic wake detection, and the micro-Doppler return from a wire in motion. All four are physically plausible. None has been demonstrated against a real airframe in a real environment. So the probability that a detection method clears validation inside a two-year window is the number that decides this one, and 65 is what a sober reading of an unproven instrument looks like. The score is not low because the idea is bad. It is lower because the first filing in a category defines a territory that does not exist yet, and a claim with nothing to cite has nothing to lean on. A new capability creates its own counter-market by definition, which means the white space on one side of a problem is usually matched by a white space on the other. Running both at once is how a map stops reading like a list of opportunities and starts reading like a set of positions.

Enforceability is the column that separates a portfolio from a pile of documents, and it penalises in a straight line. Apparatus and composition claims at the top. Methods in the middle. Software at the bottom. Two entries make the point. A cardboard airframe for expendable drones scores 88. Wax-impregnated corrugated board as a primary aerospace structural material, die-cut flat and folded into a self-jigging body. The claim is a formulation and a construction, which means a competitor's product can be bought, cut open and put through a laboratory. Thousands of the Corvo pattern of paper airframe were delivered to Ukraine, a second design is in production, and the published record shows both manufacturers leaning on trade secrecy rather than patents. The nearest patent on file covers foam deposition onto a web structure, which is a different method entirely. A composition claim on a wax, board and resin combination is the most detectable class of claim there is. Now the entry that scores 74 and should probably never be drafted. A low-cost interceptor aimed at a reconnaissance platform ten times its price scores 80 on patentability and 90 on business value, and only 70 on freedom to operate, because the space around it is already dense with more than 25,000 counter-drone patents held by names like Anduril, Elta, Securus and Boeing. Combined claims in a crowded field are narrow claims, and a narrow claim on a 3,000-dollar interceptor buys very little. The score did not say the idea was wrong. It said the space around it was occupied. Those are different sentences, and only one of them is a reason to spend money.

What makes the sheet useful is not the number at the end. It is the disagreement between the columns.

Cost asymmetry survives contact with a procurement office. An interceptor costing three to five thousand dollars against a reconnaissance drone at fifty thousand is a ratio near one to ten. Counter-drone systems currently on the market sit between 500,000 and 5 million dollars. That spread is why expendable mass production keeps being named as a critical gap, and why the 54 billion dollar programme built around the small-drone problem is larger than anything aimed at the large one. Which is where the production entry scores 82. A die-cutting line, a folding jig, an inline waterproofing step and an electronics insertion workflow are process claims, and process claims are the hardest class to enforce without walking a factory floor. Equipment claims on the specialised jig and the die are a different matter, and they are the part of that filing with teeth. The pattern repeats down the sheet. Where the money is largest, the protection is usually weakest, because coordination software and protocols describe a way of working rather than a thing that can be taken apart. Where the money is smaller and the object is dumb, the claim is strongest. That is not an argument against software. It is an argument for knowing, before the draft is written, which of the two assets is actually being purchased.

The bottom of the sheet is the most instructive row. A design methodology for integrating commodity electronics into disposable airframes scores 66, with enforceability at 50. Every part of it has already been done by somebody, and more importantly, nobody can say what infringement would mean. When the claim is a way of working, the plaintiff has to prove how a competitor worked. That is a different order of problem from buying a product and cutting it open. A 66 is not a verdict on the engineering. It is a verdict on the claim. The rule that falls out of it is uncomfortable and useful in equal measure. If you cannot describe how somebody would be caught, you do not have a patent, you have a document. Five columns. One hundred points. Equal weights, so nothing hides behind a coefficient. And a first principle that is easy to state and expensive to learn: an empty space on a map is not an opportunity. Most of the map is empty, and most of it is empty for a reason. The opportunity is the square where all five columns hold at once, and where the honest probability of surviving a challenge is written down before the money is spent rather than argued about afterwards. Two decades of building companies in twelve countries taught the same lesson in a more expensive currency. The ideas worth keeping were never the ones that survived being described. They were the ones that survived being scored. Score the empty space before you fall in love with it.
