Abstract

Research Summary: Non‐practicing entities (NPEs) are firms that accumulate and acquire patents but do not further develop or implement the patented inventions (known as patent trolling). NPEs seek to receive royalties or profits through out‐of‐court settlements in patent infringement cases. We examine how firms targeted by NPEs in NPE‐initiated litigations (i.e., target firms) shift their innovation strategies and trajectories in response to heightened litigation risks. We theorize and show that after the initial lawsuit, target firms draw more upon their in‐house technologies to reduce the legal ground for further lawsuits. Furthermore, nontarget firms in related technology areas shift their innovation activities away from those of target firms under high NPE litigation risks. These effects are more pronounced with higher innovation costs and under more competitive product markets. Managerial Summary: Non‐practicing entities (NPEs) are known as patent trolls that accumulate and acquire patents but do not further develop or implement these patented inventions. These patent trolls aim to obtain royalties or profits through out‐of‐court settlements in patent infringement cases. We investigate how firms targeted by patent trolls in litigations (i.e., target firms) change their innovation strategies and trajectories to deal with increased NPE litigation risks. After the initial lawsuit, we find that these target firms use their in‐house technologies more to reduce the legal ground for future lawsuits. Moreover, nontarget firms in related technology areas move their innovation activities away from those of target firms under high litigation risks. These effects are stronger when innovation costs are higher and under more competitive product markets. View Video S1 [ABSTRACT FROM AUTHOR]

Abstract

In order to overcome the inability of scanning multi-spectral imaging to capture multi-spectral data in dynamic scenes, a single-exposure multispectral imaging method for moving targets was proposed based on phase modulation. This method combined associated imaging technology, compressed sensing technology and spectral imaging, introduced a spatial random phase modulator into the imaging light path, modulated and compressed the three-dimensional map information data of the moving target object, then used the two-dimensional aliasing signal obtained by the detector to reconstruct the three-dimensional map information to achieve a single exposure and simultaneously obtained the three-dimensional map information of the moving target. It had the advantages of high utilization rate of light energy, short imaging time, and simple system structure. The experimental results show that when the average electron number of a single frame of CCD detection signal increases from 200 e− at intervals of 100 e− to 1300 e−, as the average rRMSE value of the electron number increases, the relative root mean square error of the reconstructed image decreases correspondingly, and the reconstruction improved image quality; when the stepper motor drives the target object to continuously move at a speed of 30 Hz, a multi-spectral reconstructed image of the moving object with better quality can be obtained; a spectrometer is used to test the spectral distribution curves of different spectrum bands in the target object, and the results obtained are basically consistent with the spectral distribution curves of the reconstructed image, which proves the effectiveness of the method. The research results provide a useful reference for the application of multi-spectral correlation imaging technology in UAV platforms, dynamic monitoring and other fields.
