Daylited

Someone has already built part of your idea. We find out who, and what it cost them.

We are an innovation firm working in four fields: electric vehicles, electric transport, artificial intelligence and hardware. Most of what kills a new product is already written down somewhere, in a granted claim, a withdrawn application or a standard nobody read. We read it first. Then we build.

Daylited AB, 559593-4240. Stockholm, Sweden.

A circuit board lifted into a cone of light in front of a shelf of unread documents A dark working scene. Behind it stands a shelf holding nine documents in half shadow. A cone of light falls from above onto a circuit board suspended in the middle, where two copper tracks draw themselves across it. A glowing line runs beneath the scene, and along the bottom stand the words prior art, claims, standards and the gap. PRIOR ART . CLAIMS . STANDARDS . THE GAP

Four fields

Narrow on purpose

A firm that claims every industry has read the record in none of them. We picked four that share the same physics and the same regulator, and we turned down the rest.

An electric vehicle in profile with the battery cells lit under the floor A vehicle drawn in thin outline from the side. Under the floor sits a battery pack with thirteen cells marked in violet, and measurement lines show the width of the pack. A glowing cable runs from the rear of the vehicle to a charging post on the right. Along the bottom stand the words pack, thermal and charge interface. PACK . THERMAL . CHARGE INTERFACE

01

Electric vehicles

Drivetrain, battery pack, thermal management and the charging interface. The part of the record that moves fastest, and the part where a late freedom to operate finding costs the most.

  • Pack architecture and cell selection
  • Charging, connectors and the standards behind them
  • Type approval and CE, planned from the first sketch
Three electric working vehicles in a depot under one shared power rail A depot seen head on. A box van, a smaller delivery vehicle and a terminal tractor stand in a row, all drawn in thin outline. Above them runs a blue rail with a streak of light gliding along it, and three violet cables drop to each vehicle. The words one connection stand above, and duty cycle measured, depot sized and grid checked stand below. DUTY CYCLE MEASURED . DEPOT SIZED . GRID CHECKED ONE CONNECTION

02

Electric transport

Everything that moves goods or people on stored electricity and is not a passenger car. Light commercial, cargo cycles, rail, port and yard equipment, and the charging that has to sit behind them.

  • Duty cycle measured, not assumed
  • Depot charging and grid connection
  • Total cost that survives an accountant
A four layer network handing its output to a document that can be checked A neural network drawn as four vertical layers of nodes joined by thin lines, where every fifth connection is violet and stronger. On the right the network hands over a document with three lines of text. Above the layers stand the words in, on device and answers for it, and below the scene stands evaluated on a set you hold. IN ON DEVICE ANSWERS FOR IT EVALUATED ON A SET YOU HOLD

03

Artificial intelligence

Models that run on a device and answer for their output. We build the ones that have to be right, not the ones that have to be impressive in a demo.

  • On device and edge inference
  • Evaluation before deployment, with the failures written down
  • The EU AI Act role settled before launch, not after
A circuit board seen from directly above with its tracks being drawn A circuit board seen from above. Three tracks in blue and violet draw themselves across the board between components, and in the middle sits a package with nine legs on each side, lit by the cone. Measurement lines show the width of the board. Above stands it has to boot, below stand schematic, layout, enclosure and EMC. IT HAS TO BOOT SCHEMATIC . LAYOUT . ENCLOSURE . EMC

04

Hardware

Boards, enclosures, sensors and the firmware between them. We build a thing you can hold, measure and take to a test house.

  • Schematic, layout and a board that boots
  • Enclosure and mechanics, printed and then tooled
  • EMC and safety pre testing before the booked slot

In the middle of the second shelf one document is pulled out and lit by the cone, showing four lines of text and a violet underline. Above stands the failures are the useful half, below stand granted, lapsed, withdrawn and rejected. THE FAILURES ARE THE USEFUL HALF GRANTED . LAPSED . WITHDRAWN . REJECTED

Patent research

The patent record is the largest engineering library on earth, and almost nobody opens it

Over a hundred million patent documents are public and machine readable. Most of them describe things that did not work, filed by people who spent real money finding that out. That is the useful half. A granted claim tells you what you cannot sell. An abandoned application tells you what not to try.

We search that record before a budget is committed. Not to file something, and not to sell you a legal opinion. We do it so the first prototype is aimed at the gap rather than at the wall.

When the search says the idea is taken, we say so on the call, and we stop. That is a cheap week rather than an expensive year.

How the search works

What we hand over

Three documents and one working object

A lens over a field of documents where a single one is lit Forty four documents lie in a grid, all faint except one that glows. A lens drawn as a circle with crosshairs and a handle lies over the field, and a bright point sits at its centre. Above stands classification first, not keywords. CLASSIFICATION FIRST, NOT KEYWORDS

The search

A landscape of what exists, who owns it, what expired and where the gap is. Every finding carries the document number, the date and the link, so you can check any line of it without asking us.

A prototype on a test bench between an instrument and a sensor An object stands in the middle of a bench, drawn as an elongated case with three lines of text and a glowing round detail. On the left stands an instrument where a blue measurement trace draws itself, on the right a sensor with four violet marks. Above stands it runs, and the number is written down. IT RUNS, AND THE NUMBER IS WRITTEN DOWN BENCH . MEASURE . RECORD . REPEAT

The prototype

A thing that runs. Board, enclosure, firmware and the software around it, with the measurements that show what it actually does rather than what we hoped it would do.

An open technical file with a mark stamped across the right hand page A binder lies open in the middle with six lines of text on each page, drawn in thin outline against a lightly filled surface. A violet round stamp with a check mark sits over the right hand page. Above stands assembled while we build, below stand risk, standards, tests and declaration. ASSEMBLED WHILE WE BUILD RISK . STANDARDS . TESTS . DECLARATION

The conformity file

The technical documentation, the risk assessment, the standards applied and the declaration your name goes on. Assembled while we build, because assembling it afterwards means building twice.

How it runs

Five steps, and you can stop after any of them

Each step ends in something you can read. If it says stop, stopping is the right answer and you keep everything produced so far.

  1. A path with a fork and one branch chosen A line that splits into two, where the upper branch is drawn in mint and the lower one dashed and faint.

    A call, no charge

    You describe the idea. We say whether it sits in one of our four fields and whether we think the record is going to be kind to you. If it is not our field we say who to call instead.

  2. A lens over a grid of small squares A grid of faint squares with a circle over part of it, and one square inside the circle drawn bright.

    The search

    Two to four weeks in the patent record, the standards and the literature. It ends in a written landscape with a recommendation, and the recommendation is sometimes to stop.

  3. An agreement with a mark on it A document with five lines of text and a violet check mark in the lower part of the page.

    The scope

    A fixed scope and a fixed price for what gets built, written before anyone starts. Changes are a new scope, not a surprise on an invoice.

  4. A bench with an instrument and a trace A screen on the left showing a drawn waveform, joined by a cable to a device on the right.

    The build

    We build it. You see it weekly, running, not as a slide. The measurements go in the file as they are taken, including the ones that disappoint.

  5. A box passed from one hand to another Two open shapes facing each other with a small square between them, moving to the right.

    The handover

    Source, schematics, board files, models and the conformity file, in your repository and under your name. We keep no copy that you have not agreed to.

The honest comparison

What you would otherwise do, and where each one is better than us

Three of these are real alternatives and we lose to each of them on something. Here is what.

If you need a filing prosecuted, you need an attorney and we will say so. If you need three hundred engineers, you need a large firm. We are the step before both, and we are cheaper than being wrong.

Asked on the first call

The questions that decide whether this is worth your time

Do you take the intellectual property?

No. Everything produced in an engagement is yours, and that is in the contract rather than in a sentence on a website. We file nothing on your invention.

The one thing we keep is general knowledge. We do not unlearn how a battery management system works because we saw yours.

Are you patent attorneys?

No, and the distinction matters. We search the record and tell you what it means for the engineering. Filing, prosecuting and giving a formal freedom to operate opinion is legal work, and it belongs with a qualified attorney. We work alongside one and we will introduce you if you do not have one.

What does the search cost, and what if it says stop?

The search is quoted as a fixed price before it starts. If it ends in stop, you have paid for a few weeks instead of a few quarters, and you keep the landscape document. That is the outcome we are least sorry about.

Do you hold certifications?

Daylited holds no management system certification today, and we will not imply one. When a project needs a certified process we say which one and who holds it.

What we do is the conformity work itself: the technical file, the risk assessment, the standards applied and the declaration of conformity that carries your name. The notified body or test house that signs off is named in the plan before the work starts.

Will you sign a non disclosure agreement before the first call?

Yes, and we prefer it. Send yours and we will sign it if it is reasonable. If you would rather use ours, ask and you will have it the same day.

How small is too small?

One person with a drawing is a normal first call. We would rather look at a sketch than at a business plan, and the search is the same search whether the company behind it has one employee or four hundred.
