Patent Foramen Ovale and Thromboembolic Complications
2010
The foramen ovale, an atrial septal defect which is essential in the fetal circulation, remains patent through adulthood in approximately 25% of the general population and so it represents the most common persistent abnormality of fetal origin. Patent foramen ovale (PFO) allows interatrial right-to-left blood shunting during those periods of the cardiac cycle in which the right atrial pressure exceeds the left one. An increasing number of pathological manifestations of PFO has been recently identified; among these, paradoxical systemic embolism, refractory hypoxemia in patients with right ventricular myocardium infarction or severe pulmonary disease, orthostatic oxygen desaturation in the r…
Patentmeklējums Eiropas patentu iestādē Latvijā pieteiktiem izgudrojumu patentu pieteikumiem.
2022
Maģistra darbā ir analizēts Latvijas Republikas Patentu valdes un Eiropas Patentu iestādes nodrošinātā projekta patentmeklējumu saturs un rezultāti. Darba mērķis ir piedāvāt scenārijus patentu piešķiršanas procedūru izmaiņām Latvijā, lai paaugstinātu nacionālajā procedūrā piešķirto patentu vērtību. Pirmajā darba daļā izklāstīta esošā situācija Latvijā, aprakstīta Patentu valdes iesaiste projektā un veicamās darbības, kā arī analizēta pieteicēju interese un patentpilnvarnieku iesaiste. Otrajā darba daļā ir analizēta patentmeklējuma ekspertīze Eiropas patentu iestādē, izklāstīts patentmeklējuma saturs un izvērtējamie kritēriji. Apkopoti un analizēti patentmeklējumu ziņojumi un rakstiskie atzi…
Need for speed? Exploring the relative importance of patents and utility models among German firms
2017
Despite the wide use of two-tiered patent systems (patents and utility models (UMs)), there is little empirical evidence about how often UMs are actually used, what kind of firms use them to protect their intellectual property, and how firms rank them relative to patents. We offer such an analysis using data from Germany. We find that larger firms are more likely to use both protection methods. Moreover, a short life cycle of products and services is associated with an increased likelihood to use UMs. The features and functioning of the German UM system are of broader interest because it has been a benchmark for several second tier patent protection systems around the world. peerReviewed
Tecniche di Produzione del Cemento Traslucido
2012
The aim of the paper is to investigate different techniques used by some companies nowadays involved in the production of panels or blocks made of translucent cement. For doing that, the patents registered all over the world starting from the 2000 have been studied in deep, in order to acquire more detailed information about the techniques of production and to overcome the limits due to the lack of information about this subject that is difficult to find in literature. Particularly, patents by LitraConTM, Luccon, Lucem, Italcementi have been investigated; these last four industries are, at the moment, the only ones able to make in Europe translucent cement elements by using different techni…
