Assignee Vs Technology

#Please note that above data is based on one member per family.

Insights:

• Only Lessmueller has an asset which talks about using interferometric measurement to determine inclination profile (For example, DE102016001661B3).
• Precitech is aggressive to file patents related to the use of interferometric measurement to determine distance and material thickness profile.
• Lessmueller patents have more filings related to adjusting the position of the laser beam based on measurement profiles where as Precitec filings are more focused on adjusting speed, laser power and intensity control.

Insights:

• Maximum number of Precitec patents were granted in 2021 and 2022.
• Patents granted in 2021 and 2023 (for e.g.  US11079218B2 & US11623299B2) were focused more on adjusting machining speed, laser power, laser focus, and/or operating parameters of the laser device based on topography measurement. These assets are primarily disclosing about measuring the topography and/or depth of the keyhole of a spot around the workpiece (i.e. weld seam) by using interferometric measurement techniques and further the measurement values are used for error detection and/or control of one or more process input variables, where the process input variables may include, for example, a machining speed, a laser power, a laser focus, and/or operating parameters of the laser device.

Measuring Profile vs Feedback for Precitec

Strength:

Precitec has aggressively filed in adjusting position of the laser beam considering different measuring profiles.

Weakness:

Precitec has very few assets considering height and position profile for adjusting the laser beam.

Opportunity:

Use of geometry profile for adjusting the laser power of a working beam can be considered as a good space for future filings.

Threat:

Precitec has some seminal patents which talk about the use of height and geometry profile measurements for providing feedback to the working beam.

Measuring Profile vs Feedback for Lessmueller

Strength:

Lessmueller has majority of their filings talking about adjusting the position of the laser beam and making use of depth and height profile.

Weakness:

Lessmueller has few fillings which talks about providing specific feedback to the working beam.

Opportunity:

Use of position and inclination profiles for adjusting the laser power of a working beam can be considered as a good space for future filings.

Threat:

Lessmueller has some seminal patents which talk about the use of measured position, geometry and inclination profiles for providing feedback to a working beam.
