Parallel Patented Products

Substantial Similarities:◦ Same structure in sampling◦ Similar user interfaces◦ Store waveform to memory◦ Display Controller/ Driver◦ Utilize Microcomputer,

RAM and ROM Distinct Differences:

◦ Analog to Digital conversion through ADC channel on the MCU

◦ Display via VGA output and controlled by FPGA◦ Playback the stored waveforms

Self Adjusting Oscilloscope

Substantial Similarities:◦ Similar trigger

methodology with slope detector

◦ Same sampling and comparison process

Distinct Differences:◦ 3-points detection

algorithm (in MCU)◦ Dynamic trigger setting

available

Digital Triggering

Substantial Similarities:◦ Input sampling with A/D

converter◦ Sampled data will be

stored in to memory waiting for processing

◦ Reconstruct signal for display

Signal Processing

Distinct Differences:o Use TIMER delay to plot x-axiso Digital reconstruction via FPGA, no D/A converter

needed

Yes because…◦ The product is already in the market and some

functions are literally the same.◦ Same tasks are performed in substantially the

same way (i.e. A/D conversion, user interface…)

No because…◦ Different way to achieve some tasks (i.e. Input

attenuation, display control and triggering algorithm).

Is it Infringement?
