Harlan Turf Equipment, its invention, its people and the cost estimates are composite; the sources cited are real. This sample is a business analysis written for a course, not legal advice.

Memo Header

To: Vice President of Engineering, Harlan Turf Equipment. From: Product Strategy Analyst. Date: March 9, 2026. Subject: Protecting the thermal-balancing firmware and the quick-swap tray. This memo is a business analysis for review by patent counsel; it is not legal advice, and every legal point in it should be confirmed by counsel before any decision.

The Invention in Plain Terms

Harlan's battery engineers have developed two things for the stand-on mower pack. The first is a routine inside the pack's sealed firmware that shifts electrical load away from the hottest groups of cells during heavy cutting. In Harlan's tests it adds about 9 percent runtime when the air temperature is above 85 degrees, when packs otherwise throttle to protect themselves. Rivals could measure the effect, longer runtime on hot days, but could not see how it is achieved without extracting and reading the firmware code. The second is a quick-swap tray that lets an operator change a pack in under a minute without tools. Anyone who buys a mower can see the tray, take it apart and copy it.

The right protection depends on these features, so they come before any discussion of law.

Four Protections, Four Scopes

A utility patent lets its owner stop rivals from building, selling or using the claimed invention, generally for up to 20 years counted from filing. In exchange, the invention is disclosed: patent applications are usually published about eighteen months after filing, so competitors can read exactly how the method works.

A trade secret protects valuable information that the company keeps secret through reasonable measures. Protection lasts as long as secrecy holds, with no fixed end. But it gives no remedy if a rival discovers the method independently or by lawfully taking apart a product it bought.

Copyright protects the firmware code as written, its particular expression, from being copied. It does not protect the idea or method the code carries out, so a rival who wrote different code achieving the same balancing would not infringe.

Trademark protects the pack's name and logo. It says nothing about how the pack works.

Patent Eligibility

For methods carried out in software, there is an added question. Since the Supreme Court's 2014 decision in Alice Corp. v. CLS Bank International, patent examiners and courts have asked whether a claim is directed to an abstract idea and, if so, whether it adds something more. A method tied to the physical control of battery cells may well pass that test, but the memo leaves the question to counsel.

Disclosure, Cost and Enforcement

A patent's cost goes beyond the fee to obtain it, which the memo budgets at roughly $30,000 per patent through issuance, an estimate for counsel to confirm. A patent is valuable only if Harlan would enforce it, and patent litigation can cost far more than obtaining the patent. Before spending that money, Harlan has to be able to show that a rival is using its invention.

How Would Anyone Know?

Detection carries the argument. If a rival used Harlan's balancing method inside its own sealed pack, Harlan could observe only that the rival's runtime on hot days had improved, which any number of other methods could explain. Proving infringement would mean obtaining and extracting the rival's firmware. A method patent that cannot be detected in use is hard to enforce, and meanwhile its publication would teach every competitor how Harlan does it.

A patent on a method no one can see in a rival's product would mostly teach rivals how to copy it.

The swap tray is the opposite case. Its design is visible to anyone who buys a mower, so secrecy cannot protect it; a rival could lawfully buy a Harlan mower and copy the tray. But infringement would also be visible, on the rival's own mowers in dealer showrooms. That makes a patent on the tray both necessary and enforceable.

Recommendation

Keep the firmware method as a trade secret, supported by encrypting the firmware, limiting access to the source code to the four engineers who maintain it and requiring confidentiality agreements from every employee and contractor who works on it. Ask patent counsel to evaluate a utility patent on the swap tray. Register the pack's name as a trademark. Rely on copyright for the code as a backstop against direct copying.

Why Protection Is Only Part of the Answer

Teece (1986) argues that the firm that profits from an innovation is often not the one with the strongest legal protection but the one with the complementary assets needed to bring it to market, such as manufacturing, distribution and service. Harlan's 400 dealers and trained technicians are such assets, and they would remain an advantage even if a rival matched the balancing method independently. Schilling (2020) notes that many firms in fast-moving technologies rely more on speed and secrecy than on patents for exactly this reason. The memo's recommendation protects what can be protected cheaply and leaves Harlan's harder-to-copy strengths to do the rest.
