Question: Who was the mother of the emperor that issued the Robot Patent?

full_context: Document 1: Fiant: A fiant was a writ issued to the Irish Chancery mandating the issue of letters patent under the Great Seal of Ireland. The name "fiant " comes from the opening words of the document, "Fiant litterae patentes ", Latin for "Let letters patent be made". Fiants were typically issued by the chief governor of Ireland, under his privy seal; or sealed by the Secretary of State, who served as "Keeper of the Privy Seal", just as the English Secretary of State did in England. Fiants dealt with matters ranging from appointments to high office and important government activities, to grants of pardons to the humblest of the native Irish. Fiants relating to early modern Ireland are an important primary source for the period for historians and genealogists. The Tudor fiants were especially numerous, many relating to surrender and regrant. A fiant often provides more information than the ensuing letters patent recorded on patent rolls. There are also fiants for which the patent roll does not list any letters patent, either because none were issued or because those issued were never enrolled, through accident or abuse. Prior to the Act of Explanation 1665, letters patent were enrolled (if at all) after they were granted; under the act, the fiant was enrolled first, and the letters issued afterwards. Thereafter the rolls, which were catalogued in the 19th century, give the same information as the original fiants.

Document 4: Economy of the Habsburg Monarchy: With the abolition of serfdom in the 18th century, the Habsburg Monarchy, with the major industrial, mining areas and forestry of regions Moravia and Bohemia leading the way, began to experience unprecedented economic growth. Beginning in 1841 per capita annual growth in the Habsburg monarchy approached 3.6 percent, a number rivaling that of neighboring Germany. While this growth was rapid and astonishing, it was not sustained.
Document 5: Joseph II, Holy Roman Emperor: Joseph II (Joseph Benedikt Anton Michael Adam; 13 March 1741 – 20 February 1790) was Holy Roman Emperor from 1765 to 1790 and ruler of the Habsburg lands from 1780 to 1790. He was the eldest son of Empress Maria Theresa and her husband, Emperor Francis I, and was the brother of Marie Antoinette. He was thus the first ruler in the Austrian dominions of the House of Lorraine, styled Habsburg-Lorraine. Joseph was a proponent of enlightened absolutism; however, his commitment to modernizing reforms subsequently engendered significant opposition, which eventually culminated in an ultimate failure to fully implement his programmes. He has been ranked, with Catherine the Great of Russia and Frederick the Great of Prussia, as one of the three great Enlightenment monarchs. His policies are now known as Josephinism. He died with no sons and was succeeded by his younger brother, Leopold II.

Document 9: Letters patent: Letters patent (always in the plural) are a type of legal instrument in the form of a published written order issued by a monarch, president, or other head of state, generally granting an office, right, monopoly, title, or status to a person or corporation. Letters patent can be used for the creation of corporations or government offices, or for the granting of city status or a coat of arms. Letters patent are issued for the appointment of representatives of the Crown, such as governors and governors-general of Commonwealth realms, as well as appointing a Royal Commission. In the United Kingdom they are also issued for the creation of peers of the realm. A particular form of letters patent has evolved into the modern patent (referred to as a utility patent or design patent in United States patent law) granting exclusive rights in an invention (or a design in the case of a design patent). In this case it is essential that the written grant should be in the form of a public document so other inventors can consult it to avoid infringement and also to understand how to "practice" the invention, i.e., put it into practical use.

Document 15: Uniformity policy: The uniformity policy was the concept of implementing Swedish law to the dominions of Sweden during the latter's time as an empire. It is symbolized by the slogan unus rex, una lex et grex unus ("one king, one law, one people") possibly coined by Johan Skytte, governor-general in Swedish Estonia, Ingria and Livonia. However, the phrase is also found in the debates on the possible union of Scotland and England in 1607, when Sir Edwyn Sandys noted King James VI & I's view that for a perfect union there should be unus rex, unus grex, una lex. Most notably, the uniformity policy aimed at abolishing serfdom then common in Estonia, Livonia and the Swedish dominons in the Holy Roman Empire (Ingermanland naturally had a free peasantry). While implemented in Livonia against the will of the local Baltic German nobles, the Estonian and Pomeranian peasants remained serfs: Estonia had voluntarily submitted to Sweden and thus had been given leeway in keeping the traditional local law code, while Swedish Pomerania had retained its traditional law code when, on behalf of the then ruling Swedish high nobility, the Peace of Westphalia granted it to Sweden while remaining part of the Holy Roman Empire, and not in a formal cession which would have resulted in the implementation of Swedish law. Swedish law was thus only introduced to Swedish Pomerania after the dissolution of the Holy Roman Empire in 1806.
