After an eventful last week for Archer Aviation (ACHR), recent SEC filings have outlined what has taken place in its legal clash with rival Joby Aviation Inc. (JOBY). At the same time, the filings revealed that a series of insider filings had taken place last week.

According to Archer’s filing with the U.S. Securities and Exchange Commission, Archer claims that certain Joby products infringe patents tied to electric vertical takeoff and landing aircraft (eVTOL). These patents cover key parts of the system, such as the aircraft itself and related power components.

Archer stated that the patents at issue involve “eVTOL aircraft, eVTOL power systems, and related components.” The firm is seeking damages and other relief as part of the case. It also asked the trade body to review whether some imports linked to the alleged infringement should be blocked.

Meanwhile, ACHR shares dropped 1.95% on Friday, closing at $6.03.

Insider Filings Linked to Stock Awards

Meanwhile, a group of Archer officers filed Form 4 and Form 144 reports tied to Archer shares. At first glance, these filings may look like insider sales. However, the details show the activity came from stock awards that vested under a pay plan.

The filings note that the first part of a 2025 performance stock award was certified by the company’s pay panel. The award vested at 53.73% of the target level. As a result, shares were issued to several officers once that goal was met.

After the shares vested, some officers filed notices of planned sales. The filings explain that these sales are tied in part to tax duties that come with the share settlement. The forms state that the proposed sales include shares needed “to satisfy tax obligations arising from the settlement of vested equity awards.”

Taken together, the filings show two separate themes for Archer investors. First, the firm is moving to defend its patent base as the air taxi race moves ahead. At the same time, the recent insider filings appear tied mainly to stock pay events rather than a shift in insider views on the stock.

Is Archer Aviation Stock a Good Buy?

Based on six recent ratings, Archer Aviation has a Strong Buy view from Wall Street. The average ACHR stock price target is $13.20, implying a 118.91% upside from the current share price.
