Skydio Patent Portfolio Analysis

One pulse, dated March 2023

A $230M Series E, announced on 1 March 2023. On a timeline it is a single moment, and that is the problem with reading a company by its funding. The pulse tells you when outside capital agreed. It says nothing about when the work started, and in this case the gap is large enough to change the story.

Skydio's first patent family was filed on 16 April 2015. By the time the Series E was announced, the company had been filing for close to eight years across three patent offices. The money is the newest fact in the file. Almost everything else predates it, some of it by most of a decade.

The money is the newest fact in the file.

156 ticks, and most of them solid

One hundred and fifty-six families. One hundred and one of them granted, fifty-five still published and pending. That is a 65 percent grant rate, and it means the solid marks outnumber the thin ones by close to two to one. A portfolio that reads this way has been through examination repeatedly rather than sitting in a queue waiting for a first look.

The thin marks matter too, because of where they sit. Filings arrived in 2021, 2022, 2023, 2024 and 2025, with 2025 the heaviest year on record at twenty-four families. The most recent published filing is dated 14 November 2025. The solid amber is history. The thin ticks are the part that has not finished happening yet.

Aircraft first, then the control problem

Unmanned aircraft classification, B64U, touches 128 of the 156 families. Below it sit two bands of equal width: B64C on seventy-nine families and G05D, control and regulating systems, on seventy-nine as well. Then B64D on forty. The airframe and the control of it are, by volume, the same story told twice.

The smaller bands are where the character shows. Image recognition, G06V, appears on thirty-five families. Traffic control systems, G08G, on thirty-four. Recent titles run to rolling shutter artifact correction for geospatially accurate imaging, a modular camera system, temperature control in base stations, and landing and alignment of an aircraft with a base station. Flight, sight, and the thing the aircraft returns to.

A small circle among much larger ones

On the same scale, Skydio is not the large shape. Over the last five years, other assignees filing in these same CPC groups include SZ DJI Technology Co Ltd with 108 families, Wing Aviation LLC with ninety-five, State Grid Corp China with eighty-seven, Kubota KK with fifty-six and Autel Robotics Co Ltd with fifty-six. Five organisations, all filing in the same classification space.

Skydio's 156 families are a total accumulated since 2015. The circles beside it count only five years. That difference is worth holding onto rather than resolving: the space is populated by organisations filing at volume, and this portfolio was built inside it, not in an empty room. The density is a fact about the classification groups, not about who prevails in them.

Who keeps coming back to this file

Four organisations cite these filings most often. SZ DJI Technology Co Ltd, eighty-nine times. GOPRO INC, sixty-two. TUSIMPLE INC, forty-one. TESLA INC, forty. The first name also appears among the heaviest filers in the same groups, which means it both files alongside this portfolio and reads it.

The other three are the interesting shape. Citation is a record of prior art being found relevant, nothing more, but the pattern here is that the relevance travels. Filings classified under unmanned aircraft, control systems and image recognition are being cited by organisations whose own filings sit elsewhere. The 244 inventors named on this portfolio, led by Hayk Martirosyan on thirty families, Adam Parker Bry on twenty-seven and Abraham Galton Bachrach on twenty-seven, were working on problems that did not stay in one classification.

Citation is a record of relevance travelling.

What the eight years actually built

Read the stages backwards and the funding event stops being the beginning of anything. A first filing in 2015. A twenty-two family year in 2017. A quiet stretch through 2019 and 2020. Then thirteen families in 2021, twenty in 2022, twenty-three in 2023, twenty-three in 2024, and twenty-four in 2025, the peak. The capital arrived in the middle of an acceleration that was already underway.

That is the point plainly: this is a filing record that the Series E joined rather than caused. The granted share is high, the newest year is the largest, and the citing organisations reach past the classification groups the portfolio sits in. What the money changed, if anything, is a question the record has not answered yet.
